Preheat your oven to 375°F (190°C) and grease a 9x13 inch casserole dish.
In a large mixing bowl, combine the shredded chicken, sliced bell pepper, sliced onion, cooked rice, black beans, diced tomatoes, corn, chili powder, cumin, garlic powder, smoked paprika, salt, and pepper. Mix well until all ingredients are evenly combined.
Spread half of the mixture evenly across the bottom of the prepared casserole dish.
Sprinkle one cup of shredded cheese over the first layer of the casserole.
Layer the remaining chicken and vegetable mixture on top of the cheese, pressing down slightly to compact it.
Top the casserole with the remaining cup of shredded cheese.
Cover the dish with aluminum foil and bake for 25 minutes.
After 25 minutes, remove the foil and bake for an additional 10-15 minutes, or until the cheese is bubbling and golden.
Once done, remove from the oven and let it cool for a few minutes before serving.
Garnish with freshly chopped cilantro and serve with sour cream or Greek yogurt on the side.
