Carefully slice the tops off each bell pepper, remove the seeds and membranes, and set them aside.
In a large mixing bowl, combine the cooked shredded chicken with the barbecue sauce and stir well.
Add in the cooked quinoa (or rice), sweet corn, black beans, smoked paprika, garlic powder, and season with salt and pepper. Mix everything together until evenly distributed.
Generously fill each bell pepper with the BBQ chicken mixture, pressing down slightly.
Place the stuffed peppers upright in a baking dish and drizzle a little extra barbecue sauce over the tops if desired.
Cover the dish with aluminum foil and bake in the preheated oven for 25 minutes.
After 25 minutes, remove the foil, sprinkle shredded cheddar cheese over each pepper, and bake uncovered for an additional 10-15 minutes.
Once cooked, remove from the oven and let cool for a few moments. Garnish with freshly chopped cilantro before serving.
Notes
Serve on a colorful plate with extra barbecue sauce for a gourmet touch.
