Cody's Chili Cornbread Casserole

1 lb. hamburger, browned, (drained)
½ Cup chopped onion
1 can diced tomatoes (do not drain)
2 can chili beans, I use Bush's Chili Beans (do not drain)
½ tsp. onion powder
3 tsp. chili powder
½ tsp. garlic salt
salt & pepper
1 cup shredded cheddar cheese
1/2 cup additonal cheddar cheese for batter (optional)
(2) packages Jiffy Corn Muffin Mix

Brown hamburger with onion and drain. Add Tomatoes, chili beans and seasonings. Simmer for 15 minutes. Put into greased 9x13 pan and sprinkle cheddar cheese on top. Mix corn bread mix according to box directions. (I add some cheese to the corn muffin mix before pouring it on top) Pour corn muffin mix on top of the chili and cheese cover completely. Bake at 400 degrees for 20 minutes or until golden brown.* I use a packet of chili seasoning mix and omit all the spices. Add about a 1/4 cup of additional water to the meat mixture.
