1) Line a baking sheet with aluminum foil and spray lightly with non-stick cooking spray. Set aside. Heat your oven to 425.
2) To make the meatballs, combine all the ingredients except for the provolone/mozzarella and the rolls. Using a tablespoon measuring spoon or cookie scoop, scoop the meat mixture out by heaping tablespoons-full and form them into meatballs. Place the uncooked meatballs on the baking sheet. Bake for 10-15 minutes or until browned (they will not be cooked through). Remove from the oven and transfer the meatballs to the sauce. Simmer for 15-20 minutes or until the meatballs are cooked through.
