Servings8 pepper halves


  • 1/2 cup white quinoa (uncooked)
  • 1 yellow onion
  • 4 cloves garlic
  • 2 medium carrots
  • 4 large bell peppers* (I use one of each color)
  • 4 oz. fresh baby spinach
  • 28 oz. can diced tomatoes (or fire-roasted)
  • 15 oz. can black beans
  • 1 Tbsp. ground cumin (or other seasoning)


  • 1 cup vegan cheese shreds (or nutritional yeast to taste)
  • Guacamole/avocado, cilantro, salsa for serving


  • Cook quinoa: Place 1/2 cup quinoa (rinsed and drained) in a small saucepan with 3/4 cup water or vegetable broth. Bring to a light boil over medium-high heat. Then reduce heat to medium-low, cover, and simmer for 15-20 minutes.
  • Meanwhile, prepare veggies: Dice onion, mince garlic, and grate/shred carrots.
  • Drain canned tomatoes, adding the tomato liquid to the bottom of a 9" x 13" baking dish. Set remaining diced tomatoes aside.
  • In an extra-large skillet over medium-high heat, sauté onion for 6-7 minutes. (I use 3 tablespoons water/broth for no-oil sauté method, adding more as needed.)
  • Add minced garlic and cumin. Stir and sauté 1 minute.
  • Add spinach (roughly chopped) and drained tomatoes. Stir.
  • When spinach is wilted, add black beans (rinsed and drained), cooked quinoa, and grated carrot. Stir and heat for 2 minutes. Salt/pepper if desired. (Optional: stir in 2/3 cup vegan cheese shreds to quinoa mixture, or nutritional yeast to taste.)
  • Preheat oven to 350°F (176°C).
  • Cut bell peppers in half lengthwise. Remove stems, seeds, and inner ribs. Fill each pepper half with a heaping amount of quinoa mixture. Pack it down well with a spoon to fill all the crevices*. Place filled peppers in baking dish on top of the tomato liquid.
  • Cover the dish with foil. Bake for 75 minutes. (To add cheese: After 1 hour of baking, remove foil and sprinkle peppers with remaining 1/3 cup cheese. Return to oven and bake uncovered 15 minutes.)
  • Drizzle with pan juices before serving. Serve with guacamole/avocado, salsa, nutritional yeast, etc. if desired.


*Peppers: If you can't find large bell peppers, use 5-6 small/medium peppers. You may have a little leftover quinoa mixture. It's great in a burrito or simply as a salad.
Nutrition: Estimated nutritional content is for each pepper half (without the optional cheese and toppings).
