Recipe Friday - Debbie's Corn Bread

1 box Jiffy cornbread
1 small chopped onion
1 stick butter
1 small (8 oz) container sour cream
1 cup of shredded cheese (I use sharp cheddar)

Mix cornbread according to package directions. Spread in a greased pie pan. Microwave the onion & butter until the butter melts. Then mix sour cream & cheese with the onion & butter. Spread this mixture over the cornbread. Bake at 400* until done (about 30 minutes).

This is great with chili.
