Dining Green in a Pandemic

Author: Adam Elkins ‘23

For everyone on campus, we’re all so excited that the dining halls have opened back up, allowing us to eat hot food and spend time together with friends. Of course, they don’t look the same as they did last year. We’re still living during a pandemic, and as a result, we’re not able to implement many of our former sustainable dining practices. Nevertheless, there are still so many small ways you can practice sustainability while eating. I hope this post gives you some practical and simple ideas for protecting the environment–while you protect yourself!

Choose to Reuse

Bring reusable utensils and say no to plastic silverware. Plastic silverware isn’t recyclable, is deadly to sea creatures, and takes centuries to decompose1. While the dining halls can’t offer everyone reusable silverware, bringing your own utensils is perfectly safe, better for the environment, and easy to clean: simply wash in hot water with soap! It’s also cheap; the U-store sells metal cutlery for just a few dollars.

Along this vein, try drinking from a reusable water bottle. Just remember to fill it up at your closest filtered water station beforehand, because they can’t be filled in the dining hall. In addition, make sure to avoid other unnecessary single-use plastics, such as packaged foods and drink lids, and since student composting isn’t active, prevent food waste by only taking what you can eat.

Drink Local

While drinking water from a recyclable can is better than using plastic, it’s still not as sustainable as a reusable bottle. The water in these cans is often shipped across the country consuming fossil fuels, and there’s no guarantee that the cans end up recycled anyway. Instead, try one of the hundreds of filtered bottle-filling stations across campus, which supply water from the local watershed2. If you don’t have a filling station in your dorm, do not fear! You can request one to be installed here; however, tap water from the sinks on campus is perfectly safe and comes from the same place as the filling stations. I drink it every day myself!

Recycling

Recycle! …just be smart about it. Recycling guidelines are different everywhere, and just because you could recycle something in your hometown doesn’t mean it can be recycled on campus. On the flip side, you might be able to recycle materials that went to the landfill at home! Download the Recycling on Campus app for more information on what can and can’t be recycled. If too many non-recyclable materials, like the dining hall meal cartons, are put in the recycling, they can contaminate the whole batch. In that case, materials that would have been recycled are instead sent to the landfill. So remember: When in doubt, throw it out! Also, there aren’t recycling bins in the dining halls yet, but there are typically some just outside. We’re working with dining staff to change this, so for now, just make sure to hold onto your cans until you see a bin. 

So there you have it! Just remember that the changes in our dining halls are happening for an important reason. While it’s a shame to have to pause some of Princeton’s most sustainable practices, there are still valuable steps that you can take to make a very real difference. Feel free to share with us how you practice sustainability in the dining halls!

Sustainable Meals for Busy Students: Black Bean Soup

Author: Camellia Moors ‘22

As it gets colder outside for many of us, soup is a perfect way to warm up! Instead of choosing meat-based options like chicken soup, however, try opting for something vegetarian-based. This recipe’s main feature, black beans, involve far fewer carbon emissions than meats like beef. It can also be made more sustainable through customizations, like buying dried beans in bulk, which reduces packaging and saves money, or by using in-season/local toppings (in my case, I used Florida avocados!). 

Regardless of how you choose to swap out ingredients, this recipe is quick, cheap, and easy to make. Perfect for busy students!

Ingredients:

  • 1 Tbsp extra-virgin olive oil
  • 1 medium yellow onion, chopped
  • 1 carrot, peeled and sliced into thin rounds
  • 3 garlic cloves, pressed or minced
  • 2 tsp ground cumin
  • Red pepper flakes (to taste; begin with ¼ tsp)
  • 2 15 oz cans black beans, rinsed and drained
  • 2 cups vegetable broth
  • Salt and black pepper (to taste)
  • Optional: 
    • 3 celery ribs, finely chopped
    • Fresh cilantro (to taste)
    • 1 tsp sherry vinegar or 1 Tbsp tablespoons fresh lime juice (to taste)
  • Optional garnishes: Avocado, cilantro, tortilla chips, etc.

Steps:

Step 1: Prep all of your ingredients. (TIP: If you decide to use fresh cilantro, trimming the leaves is made a bit easier by running the herb through the prongs of a fork to de-stem the plant in bulk. You don’t have to do this, but it goes a bit faster!)

Step 2: Heat the olive oil in a large soup pot over medium heat. Add the onions, celery (if desired), carrot and a light sprinkle of salt. Cook, stirring occasionally, until the vegetables are soft (about 10 to 15 minutes).

Step 3: Stir in the garlic, cumin and red pepper flakes and cook until fragrant (about 30 seconds).

Step 4: Pour in the beans and broth and bring to a simmer over medium-high heat. Cook, reducing heat as necessary to maintain a gentle simmer, until the broth is flavorful and the beans are very tender, about 30 minutes.

Step 5: Transfer the soup to a stand blender and add in the cilantro, lime juice, and black pepper, if desired. Securely fasten the lid and blend until smooth (keep in mind that the soup will still be hot and steam will escape when you open the lid). Alternatively, use an immersion blender in the soup pot.

Step 6: Return the pureed soup to the pot and add in any additional seasonings to taste. Serve with your choice of toppings (I went with Florida avocado, sriracha, and extra cilantro).

Sustainable Meals for Busy Students: Vegan Wawa Gobbler Hoagie

Author: Annika Hsi ‘23

This recipe is a quick and easy way to repurpose Thanksgiving leftovers and reduce food waste. Food waste can be a big problem, especially during the holiday season, with over 450 million pounds of Thanksgiving food being wasted each year. 

For this homemade version of Wawa’s Gobbler hoagie, my leftovers happened to be plant-based, but since this recipe is super customizable, you can always experiment with whatever Thanksgiving dishes you have in the fridge!

Ingredients:

  • Bread (i.e. hoagie roll, sourdough, etc.)
  • Thanksgiving leftovers, such as:
    • ½ cup of stuffing or mashed potatoes
    • 3-4 slices of vegan turkey or chicken
    • ¼ cup of roasted vegetables
    • Gravy or cranberry sauce

Instructions:

Step 1: Cut and toast the bread.

Step 2: Layer on the ingredients. I usually put stuffing or mashed potatoes on the bottom, then vegan turkey/chicken or roasted vegetables on top. If you don’t have your own leftovers or if you want to experiment with some plant-based foods, here are some ideas for sandwich fillings:

  • Stuffing: I replaced the butter with Earth Balance and the eggs with 2 tbsp of ground flaxseed mixed with 5 tbsp of water.
Image Credit: Annika Hsi ‘23
  • Roasted Vegetables:  I coated Brussels sprouts with olive oil, salt, pepper, and thyme. Then I baked them at 415°F for 30-45 min.

Sustainable Meals for Busy Students: Apple Crisp

Author: Joe Himmelfarb ‘24

Sometimes we want to eat something warm, sweet, and comforting––something that feels close to home. At the same time, we want to indulge guilt-free, in terms of both our health and the carbon footprint of our food. To appease these cravings, look no further than this apple crisp recipe and look fast because most apples are almost out of season! This recipe is not only delicious, fairly easy to make, and highly nutritious but also a great way to practice sustainable dining. 

Farmer’s markets are still offering a variety of fresh, seasonal apples, but fear not if you cannot reach one: groceries at this time of year often stock locally produced apples. Eating locally has numerous benefits for the environment and is indeed inseparable from the notion of sustainable agriculture. It has been found that “conventional food distribution [is] responsible for 5 to 17 times more CO2 than local and regionally produced food.” Furthermore, opting for local produce supports small family farmers who often promote sustainable agriculture in various ways like limiting their use of synthetic inputs and industrial processing tools. That said, it is also important to take advantage of seasonality: out-of-season produce, even when grown locally, uses more resources than in-season produce grown locally. For example, “More water is needed to…grow strawberries in New York in the dead of winter.”

A final note before the recipe: cooking apple crisp offers an excellent opportunity to test out new kinds of apples. While most apples are not as sweet as our beloved Honeycrisps, Fujis, and Galas, tarter apples shine when it comes to baking. I prepared this apple crisp using Stayman, Jonagold, Rome, Nittany, and Goldrush apples that I purchased at my local farmer’s market. If you are able to visit a farmer’s market, I would highly recommend asking vendors for their opinion on the best baking apples.

Ingredients:

Apple Mixture:

  • 5-6 apples, roughly chopped
  • 1 tbsp lemon juice
  • 2 tsp cinnamon
  • 1-2 tbsp maple syrup
  • Salt (optional)

Crumble: 

  • 1 ½ cups of rolled oats
  • (Roughly) ½ cup walnuts
  • 2-3 tsp cinnamon
  • 2-3 tbsp maple syrup
  • Salt (optional)

Instructions:

Step 1: Preheat oven to 350°F. 

Step 2: Blend oats or mash manually until coarsely ground. 

Step 3: Blend or mix in the remaining crumble ingredients, adding more or less cinnamon, maple syrup, and salt as desired.

Step 4: Roughly chop apples. 
Optional Step: For softer apples, microwave chopped apples for 5 minutes.

Step 5: Mix apples with the rest of the mixture ingredients in a baking dish.

Step 6: Cover apple mixture with crumble.

Step 7: Bake for 35-40 minutes.

Step 8: Enjoy!

Optional Step: For a light, delicious plant-based pairing, try nice cream. To prepare: freeze a few ripe bananas, and then blend them while adding small amounts of water or plant-based milk until a creamy consistency is reached. You can also try blending in other flavors like vanilla, cocoa, or fruit like mango and strawberry.

Sustainable Meals for Busy Students: Oven-Baked Sweet Potato Fries

Author: Alev Studenikina ‘23

Everyone loves sweet potatoes! They can be cooked in a variety of ways and taste especially wholesome in the Fall season with the anticipation of Thanksgiving.

While, sadly, most of us right now cannot savor food marvels like Curried Sweet Potato & Lentil Stew or Maple Glazed Sweet Potato Cake made by the Campus Dining chefs, sweet potatoes are such an amazing ingredient that even a simple dish can be mouthwatering. 

Also, did you know that sweet potatoes are the way to go in terms of sustainable food production that would address the challenges of feeding the world population? The sweet potato “provides more calories per hectare and per growing month than all the major grain crops” while containing vitamins A, C, B6, manganese, potassium and antioxidants. After the discovery of the Covington sweet potato variety, well-suited to the climate in North Carolina, billions of pounds of sweet potatoes can be grown annually in this state, and sweet potatoes are farmed in other states such as California, Mississippi, Louisiana, Arkansas, and Louisiana. This means that sweet potatoes are relatively locally grown for many people in the USA, giving them a lower overall carbon footprint compared to other foods.

Enough of the facts – here is a simple recipe for healthy and delicious oven-baked sweet potato fries!

Ingredients:

  • 2 sweet potatoes
  • Vegetable oil (I used olive oil)
  • Salt (to taste)
  • Spices (turmeric and paprika, to taste)

Steps (15 min prep time + 30 min in the oven):

Step 1: Pre-heat the oven to 180°C (350°F).

Step 2: Wash the sweet potatoes and cut them into approximately fry-sized pieces.

Step 3: Line a tray with baking paper and transfer the sweet potato pieces onto it.

Step 4: Add a drizzle of olive oil, plus the salt, turmeric and paprika.

Step 5: Mix everything together so that each piece gets coated with the oil and spice mixture.

Step 6: Spread the pieces out on the tray so that there is some space between them (otherwise they will not get a nice crust). I could fit one cut-up sweet potato on the tray, so I baked the two in turns.

Step 7: Put the tray in the oven for 25-30 min. After 20 min, turn on the grill setting or the fan inside the oven to dry out the “fries” a bit.

The result:

There was actually more from the two sweet potatoes that I used, but these “fries” are irresistible when they are just out of the oven, so quite a few were gone before I got to take this picture!

Sustainable Meals for Busy Students: No Parm Eggplant Parmesan

Author: Kara Steele ‘21

Have you ever been to your local farmer’s market? Going to the farmer’s market can be a really fun way to support local businesses and connect with the community (especially now since they are mostly outdoors and socially distanced). Visiting farmer’s markets can also be a good way to learn more about the crops grown in your area as markets often offer local, seasonal produce. While it is fun to try new things and eat super fresh food, eating local, seasonal food can also reduce your environmental impact and food waste. By eating food grown closer to you, you can reduce the energy needed to transport the food to you and reduce necessary packaging. Eating local can also minimize food waste as over 50% of food waste happens when the food is in transit or storage.

Lately I have been finding a lot of eggplant at my local farmer’s market, so I went on a hunt for some tasty eggplant recipes. The winner so far is plant-based eggplant parmesan, which is featured below.

Photo from page 103 of 30 – Minute Vegan Dinners by Megan Sadd.

Ingredient list: 

  • Two to three small to medium sized eggplants
  • Salt (1 tbsp + ¾ tsp)
  • Water
  • Flour (4 tbsp)
  • Breadcrumbs (Italian preferred)
  • Garlic powder
  • Italian seasoning
  • Pepper
  • Nutritional Yeast
  • Marinara sauce 
  • Spaghetti 
  • Optional: Parmesan or plant-based cheese

Steps:

  1. Wash and cut the eggplant into quarter inch slices. I usually use two to three small- to medium-sized eggplants. Fill a bowl with a tablespoon of salt and a quart of warm water and mix. Then add two more quarts of cold water and the eggplant slices and let sit for 30-45 minutes.
  2. Preheat the oven to 450˚F.
  3. Prepare your dredging liquid. In a bowl add about a ½ cup of water and 4 tbsp of flour and stir. 
  4. Prepare the breading. In a separate bowl, add: 2 cups of breadcrumbs, ¾ tsp salt, 1 tsp garlic powder, 2 tsp Italian seasoning, 1 tbsp nutritional yeast, and pepper to taste. Pour this mixture onto a plate.
  5. Prepare your assembly line. Line up the bowl of dredging liquid, plate of breading, and a pan lightly greased with olive oil.
  6. For each slice of eggplant, dredge it in the dreading liquid and coat it with the breadcrumb mixture and put it on the pan. If the breadcrumbs on the plate get too saturated with liquid they may stop sticking, so mix in some dry breadcrumbs if needed.
  1. Bake the eggplant slices for 18 minutes, then flip them and cook for another 10 minutes. Check their tenderness with a fork. If the eggplant is still chewy or tough, you can cook it longer until it becomes more tender and less bitter.
  2. If you want, you can add a sprinkle of parmesan to the slices when they have about 5 minutes left to cook, but you can opt to leave this step out for a more plant-based meal.
  3. I like to serve it with marinara sauce and spaghetti, but feel free to mix and match as you prefer! Enjoy!
