Sarah gave me this one when I was in Dallas. It's really good and you can substitute chicken or put in rotel tomato etc.
1 lb. hamburger brown and drain
4 potatoes- wash, slice, boil until tender
1 onion sliced
2 or 3 zucchini wash slice boil with onion
1 can tomatoes
1 can tomato sauce
1 cup shredded cheesesLayer hamburger, potatoes, zucchini, tomato sauce, tomatoes, onions, cheese.
Bake 350 degrees 25-30 minutes.
When you slice the potatoes and onions do them the round of the potato and onion.
