Rolls or buns (I love these soft tear-shaped rolls from Sam's Club)
Frozen Italian Meatballs (again...freezer section at Sam's)
Shredded mozarella and cheddar cheese
1 can or bottle favorite spaghetti sauce (I use Hunts Traditional from the can)
Brown desired amount of meatballs in a frying pan. Transfer to a crockpot and pour spaghetti sauce over the top. Cook on low for about an hour and then turn to warm until you are ready to eat. Slice buns and toast in a 400 degree oven for about 2-3 minutes. Place 4 meatballs and desired amount of sauce on buns. Cover with cheese and return to oven until cheese is melted and bubbly and edges of bread start to brown.
