Cornbread Casserole

I thought that I got this recipe from a Mr. Food cookbook, but I can't find my original back, and since it is so simple, I usually make it from memory, not actually from a printed recipe.

Cornbread Casserole

1 LB hamburger
1 can creamed corn
1 box corn muffin mix
1 cup shredded cheddar cheese

Brown hamburger, drain.  Mix in creamed corn and place in a casserole dish or 9x13" baking dish.  Prepare corn muffin mix according to box and pour over top.  Sprinkle cheese on top and bake at 400° for 30 minutes.
