Chili and Cornbread Casserole

I combined two recipes and came up with this...

1 lb. Ground beef
1 can (15-16 oz) chili beans, undrained
1 c. salsa
1 can Rotel diced tomatoes with cilantro and lime juice
3 tsp. chili powder
1 tsp. cumin
1 pkg. (15 oz) honey cornbread mix
1 1/2 c. Mexican cheese
Sour cream

Brown the beef and drain, add beans, salsa, diced tomatoes, chili powder, and cumin. Heat until bubbly. Make cornbread mixture according to package. Spread half of cornbread mixture on bottom of 2-quart casserole dish. Layer beef mixture on top. Spread remaining cornbread mixture on the top just around the edges. Leaving a hole in the middle. Bake at 400* for 18-20 minutes. Then sprinkle with cheese and bake for another 5 minutes until cheese is melted and starting to crisp. Remove from oven. Serve with a dollop of sour cream on top.
