1 (9 inch) deep dish frozen pie crust
1 cup shredded mozzarella cheese
1 cup shredded Cheddar cheese
1 (8 ounce) can cream cheese, chilled and diced
1 (10 ounce) package frozen chopped spinach, thawed and drained
1 (8 ounce) container frozen whipped topping, thawed
1 (9 inch) prepared graham cracker crust
Preheat oven to 375 degrees F (190 degrees C).
In a medium bowl, mix mozzarella, Cheddar, cream cheese and spinach. Spread a layer of the mixture in the bottom of a 9x13 inch baking dish.
In a second bowl, beat together the Cheddar cheese and spinach. Layer 3/4 of the cheese mixture, then the remaining cheese mixture, then the remaining spinach. Fold in the creamed cheese mixture, then the remaining spinach. Spread remaining cheese mixture over the top of the pie, then layer the remaining spinach over the tomato layer.
Bake in the preheated oven for 25 minutes, or until the sauce is bubbly and lightly browned.
