Preheat oven to 350.
Cook the beef, garlic, and onion until evenly browned.
Wash and remove and discard the tops, seeds, and membranes of the bell peppers. Arrange peppers in a baking dish with the hollowed sides facing upward.
In a bowl, mix the browned beef, cooked rice, tomato sauce, spices, black beans, roasted green chiles, and corn.
Top with shredded cheese and cover with foil.
Bake 30 minutes to 1 hour depending on the size of bell pepper in the preheated oven, cook until the peppers are tender.
Let cool 15 minutes. Top with cilantro. Enjoy!
