In a large mixing bowl, combine the cooked rice, shredded chicken, corn, black beans, diced bell peppers, and half of the cheddar cheese.
Pour in the enchilada sauce and sprinkle with ground cumin, smoked paprika, garlic powder, onion powder, salt, and pepper. Mix everything well until all ingredients are coated with the sauce.
Grease a 9x13 inch (or similar size) casserole dish with non-stick cooking spray. Pour the mixture into the dish, spreading it evenly.
Top the casserole with the remaining shredded cheddar cheese, making sure to cover the entire top.
Cover the dish with aluminum foil and bake in the preheated oven for 25 minutes. After 25 minutes, remove the foil and bake for an additional 10-15 minutes, or until the cheese is bubbly and slightly golden.
Once baked, remove from the oven and let it sit for 5 minutes before serving.
Garnish with fresh cilantro and sliced jalapeños, if desired.
Notes
Serve in a vibrant dish and accompany with sour cream or avocado slices.
