1. Preheat your oven to 375°F (190°C) and line a 9×13-inch baking dish with foil for easy cleanup.
2. Cut bell peppers in half lengthwise and remove all seeds and white membranes—be thorough here.
3. In a large bowl, combine the cooked quinoa, black beans, corn, salsa, cumin, and chili powder. Mix really well until everything’s evenly distributed.
4. Place pepper halves cut-side up in your prepared baking dish and divide the quinoa mixture evenly among them, packing it in gently.
5. Cover the entire dish tightly with foil and bake for 30 minutes (check at 25 if your oven runs hot).
6. Remove foil, sprinkle cheddar cheese over each stuffed pepper, and bake uncovered for another 10 minutes until cheese is melted and bubbly.
7. Let rest for 5 minutes, then garnish with fresh cilantro before serving.

Notes:

• Seriously, pick peppers that can stand upright—wobbly ones are frustrating
• Every oven runs differently, so trust your eyes over the timer
• The filling should be moist but not soupy when you stuff the peppers
• Don’t overstuff them or the filling will spill out as it cooks

Storage Tips:

• Refrigerate leftovers for up to 4 days in covered containers
• Reheat in a 350°F oven for 15 minutes or microwave for 2 minutes per pepper
• Don’t freeze these once cooked—the peppers get too soft
