Ham and Corn Casserole

*16 oz. cubed ham *1 can of whole kernel corn, drained *1 can cream-style corn *1 8 oz package corn muffin mix *1 cup of sour cream *1/2 stick butter, melted *1 to 1 1/2 cups shredded cheddar cheese. Preheat oven to 350 degrees F. Saute ham in a frying pan until browned (to get most of the moisture out). In a large bowl, stir together the ham, 2 cans of corn, corn muffin mix, sour cream and melted butter. Pour into a greased 9 by 13 inch casserole dish. Bake for 45 minutes, or until golden brown. Remove from oven and top with Cheddar. Return to oven for 5 to 10 minutes, or until cheese is melted. Let stand for at least 5 minutes and then serve warm.
