Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F. Slice the tops off 4 large bell peppers and remove seeds and membranes. Set aside.
  2. Step 2: Cook 1 cup rinsed quinoa with 2 cups water in a medium saucepan over medium heat. Bring to a boil, then reduce heat to low, cover and simmer for 15 minutes until water is absorbed. Fluff with a fork.
  3. Step 3: While quinoa cooks, heat 2 tbsp olive oil in a skillet over medium heat. Add 1 diced onion and 3 minced garlic cloves, sauté for 5 minutes until softened and fragrant.
  4. Step 4: Stir in 1 tsp ground cumin and 1 tsp smoked paprika, cooking for 1 minute to release aroma.
  5. Step 5: Add cooked quinoa, 1 can (15 oz) drained black beans, 1 cup frozen corn kernels, 1/4 cup chopped fresh cilantro, 1/2 tsp salt, and 1/4 tsp black pepper to the skillet. Mix well and cook for 2 more minutes.
  6. Step 6: Spoon the quinoa mixture evenly into the prepared bell peppers and place them upright in a baking dish.
  7. Step 7: Sprinkle 1 cup shredded cheddar cheese over the tops of the filled peppers.
  8. Step 8: Cover the dish with foil and bake for 25 minutes. Remove foil and bake an additional 10 minutes until peppers are tender and cheese is melted and golden.
  9. Step 9: Let cool for 5 minutes before serving.
