16 oz. frozen pierogis - you can use any flavor you prefer. I typically use potato & cheddar.
1 (15 oz) can tomato sauce
1 (14.5 oz) can diced tomatoes
1/2 a large green pepper, diced
1/2 cup pepperoni, cut into small pieces
1 1/2 cups shredded mozzarella cheese
To assemble:
Place frozen pierogi in a baking dish in a single layer. In a bowl, mix together tomato sauce, diced tomatoes, diced green pepper & pepperoni. Pour mixture over frozen pierogi & top with cheese. Cover baking dish with with foil & freeze.
To serve:
Thaw overnight, then bake 20 - 25 minutes at 350 degrees, or until cheese is melted & pierogi are heated through.
Adapted from a recipe I found on the side of a box of Mrs. T's pierogis years ago :)
