Heat oven to 350°F. Line a large cookie sheet with parchment. Cook meatballs in microwave as directed on package and cool slightly.

Unroll dough and separate into 2 long rectangles. Place 1 inch apart on cookie sheet; press edges and perforations to seal. Press each sheet into a 14x4-inch rectangle.

Sprinkle mozzarella down the center of both pieces of dough. Space 8 meatballs evenly over cheese on each. Spoon pasta sauce over meatballs.

Starting at one end, stretch and pull both sides of dough up and between each meatball; press together to seal. Score dough between meatballs with a table knife.

Mix melted butter, Italian seasoning and garlic powder. Brush over dough and sprinkle with Parmesan.

Bake 26-30 minutes until dough is deep golden brown and meatballs reach at least 165°F. Serve with additional warm pasta sauce for dipping.
