cornbread casserole

1 pound ground beef (can use ground turkey instead)
1 onion, chopped
1 can tomatoes, partially drained
1 can pinto beans, drained
1 teaspoon salt
1 box corn bread mix (I use this cornbread recipe)

Saute beef and onions until well done. Add tomatoes, beans and salt. Pour into a 2-quart casserole and top with cornbread mixed according to package directions. Bake at 350° F about 35 minutes. Serve with chow chow.
