Heat oven to 450°F. Line 15x10x1-inch baking pan with foil. Spray with non-stick baking spray. Top with a cooling rack (for draining).
Remove Johnsonville sausage from casing. Place in a bowl and break it up.
Add all the remaining meatball ingredients except cheese in a bowl. Mix well.
Shape mixture into 24 meatballs. Press 1 cheese cube into the center of each meatball. Use your hands to cover meat mixture over cheese completely. Place on prepared rack.
Bake for about 13-15 minutes or until no longer pink. Serve with Barilla pasta and sauce, if desired. Sprinkle with remaining mozzarella cheese (or save for another use).
