Upside Down Pizza Casserole

1 can refrigerator pizza crust

1 box frozen spinach, cooked and drained

1 lb. hamburger or Italian sausage, cooked and drained

1 jar spaghetti sauce

2 c. mozzarella cheese

Combine hamburger and sauce in a 9x13 foil pan.  Add additional pizza “toppings” as desired.

Top with spinach and cheese.  Freeze. 

To prepare:  Thaw.  Lay crust over top and pinch sides to the side of the pan.  Bake at 400° for 10-15 minutes.

(I used the above ingredients for 2 8x8 pans. Cut off additional crust and use for breadsticks.)
