That sounds excellent and all but I don’t think I’d have the hours in the day to make everything from scratch so store bought it is!
Ingredients
1 bag of frozen meatballs
1 jar of spaghetti sauce
1 cup Kraft shredded mozzarella cheese
1 cup shredded Italian blend cheese
½ cup shredded parmesan cheese
1 loaf fresh Italian bread sliced.
Instructions:
Preheat oven to 400.
Place frozen meatballs in sauce pan with spaghetti sauce and heat until warmed through stirring often to prevent meatballs from sticking together.
Grease a 9 x 13 pan
Pour sauce and meatballs in center of pan.
Sprinkle each variety of cheese over top in order as they appear above.
Take slices of bread and line the bap all around keeping the meatballs toward the center of the pan.
Bread will be standing up in the pan.
Bake for 15 minutes or until cheese is melted and bubbly.
