Boats
Preheat oven to 450°
Take a hoagie roll and cut around the top with a serrated knife.
Pull the top off and tear out the middle to make a boat. Discard the bread or save it for another purpose such as bread crumbs.
Take 2 thick slices of mozzarella cheese and place in the bottom of the boat. Brush the rest of the exposed bread inside with olive oil.
Bake until cheese melts.
Place 3 meatballs into each boat and then top with sauce and sprinkle with fresh grated parmesan cheese.
