Make the garlic butter by combining all of the ingredients and mixing well.
Arrange the rolls in a 9x13" pan so that they fit snugly. Use a serrated knife to cut a hole out of the middle of each roll. Brush the tops and side the hole with the garlic butter mixture evenly. Bake for 6-8 minutes to melt the butter and toast the rolls. Then remove from oven.
Mix the mozzarella and parmesan cheese. Use half the cheese to place a small amount in each of the holes in the rolls. Stuff a meatball into the hole on top of the cheese, then top the meatball with a dollop of sauce. Sprinkle the remaining half of the cheese over the top of the sandwiches.
Bake for 20-25 minutes or until the meatballs are hot and the cheese is melted.
