Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. Slice 4 large poblano peppers in half lengthwise and remove seeds and membranes carefully. Place them cut-side up on a baking sheet and brush with 2 tbsp olive oil. Roast for 15 minutes until skins soften.
  2. Step 2: While peppers roast, bring 2 cups water to a boil in a medium saucepan. Add 1 cup rinsed quinoa, reduce heat to low, cover, and simmer for 15 minutes until water is absorbed and quinoa is fluffy.
  3. Step 3: In a large bowl, combine the cooked quinoa, 1 can (15 oz) drained and rinsed black beans, 1 cup corn kernels, 1/2 finely chopped red onion, 1 minced jalapeño, 1 tsp ground cumin, 1 tsp chili powder, 1/4 cup chopped cilantro, 1 tbsp fresh lime juice, 1 tsp salt, and 1/2 tsp black pepper. Mix well.
  4. Step 4: Spoon the quinoa and bean mixture evenly into the roasted poblano halves. Top each stuffed pepper with 1 cup shredded Oaxaca or mozzarella cheese.
  5. Step 5: Bake stuffed peppers for an additional 12-15 minutes until the cheese is melted and golden. Serve warm garnished with extra cilantro if desired.
