How to Make It
Preheat oven to 400°.
Combine first 8 ingredients in a bowl. Shape into 24 meatballs.
Arrange meatballs evenly on a jelly-roll pan coated with cooking spray. Bake at 400° for 20 minutes or until done. Turn oven up to 450°.
Combine meatballs and pasta sauce in a medium saucepan. Place over low heat until sauce is warm, stirring often. Keep warm.
Hollow out center of each hoagie roll. (Reserve soft bread for another use.) Spoon 6 meatballs into each roll. Spoon sauce evenly over meatballs. Top each sandwich with onion and 2 tablespoons mozzarella cheese.
Arrange sandwiches evenly on a baking sheet. Bake at 450° for 5 minutes or until cheese melts.
