Ingredients

  • 6 medium bell peppers halved, seeds removed
  • 1 cup uncooked quinoa rinsed
  • 2 cups low-sodium vegetable broth
  • 1 tbsp olive oil
  • 1 small onion diced
  • 2 garlic cloves minced
  • 1 can 15 oz diced tomatoes
  • 1 can 15 oz black beans (drained)
  • 1 cup frozen corn thawed
  • 1 tsp cumin
  • 1 tsp paprika
  • ½ tsp salt
  • ¼ tsp black pepper
  • 1 cup shredded Monterey Jack cheese

Optional toppings: cilantro, avocado, sour cream

Instructions

  • Cook quinoa: In a saucepan, combine quinoa and vegetable broth. Bring to a boil, then simmer covered for 15 minutes. Let sit 5 minutes, then fluff with a fork.
  • Prep peppers: Cut bell peppers in half lengthwise; remove seeds. Place in a baking dish, cut-side up, with ¼-inch water in the bottom.
  • Make filling: Heat olive oil in a skillet. Sauté onions for 3 minutes, add garlic, and cook 1 minute. Stir in tomatoes, black beans, corn, and cooked quinoa. Season with cumin, paprika, salt, and pepper. Cook 5 minutes.
  • Stuff peppers: Spoon filling into pepper halves. Top with cheese.
  • Bake: At 375°F for 30–35 minutes, until peppers are tender and cheese is melted.
  • Serve: Garnish with cilantro, avocado, or sour cream.

Notes

  • Storage: Keep leftovers in an airtight container for 3–4 days.
  • Freezing: Freeze baked peppers for up to 3 months. Reheat at 350°F.
  • Vegan option: Omit cheese or use dairy-free shreds.
  • Shortcut: Use pre-cooked quinoa to save time.
