1Preheat the oven to 400 degrees.
In a 12" oven safe skillet, cook ground beef until no longer pink. Drain.
2To the cooked ground beef, add black beans, tomatoes, chili beans, corn and tomato sauce. If you want an extra kick of spice, add 1-2 teaspoons of chili powder. Stir together and bring to a low boil. Simmer for ten minutes.
3While the chili is simmering, mix up the cornbread using the box mix plus the ingredients it calls for, such as eggs, milk, and oil or butter. Add the cup of shredded cheddar and gently stir just enough to incorporate.
4Remove chili from heat and drop cornbread batter by spoonfuls over the chili, gently spreading to the edges.
5Bake in a 400 degree oven for about 20 minutes, or until the top is nice and golden brown. Check the cornbread for doneness before dividing into bowls and serving
