Preheat oven to 375ºF.

To make garlic butter, place all ingredients in a medium mixing bowl. Mix well until uniform throughout.

Place rolls in a greased 9x13-inch pan.

Using a serrated knife, cut a hole out of the middle of each roll.

Using a butter knife, spread garlic butter in and around the holes that you cut out.

Bake rolls for 6-8 minutes or until the butter is melted.

In a small bowl, combine mozzarella and parmesan cheeses.

Even distribute half of the cheese mixture between the 24 holes.

Press one meat ball into each hole followed by a spoonful of marinara.

Finally, sprinkled the remaining cheese mixture over top of the rolls.

Bake for 20-25 minutes or until cheese is melted and slightly golden.
