Mix all together in a large bowl. Pour into a buttered 13x9 casserole dish. Pour on the biscuit topping (below). Bake at 350 degrees for an hour or until bubbling.
Biscuit topping:
Combine dry ingredients. Cut in oil using fingers or a food processor to get the texture of fine crumbs. (This mix can be made in larger quantities and stored in an airtight container in the refrigerator.) Stir milk or water into mix, just until moistened (don't over mix).
