Preheat your oven to 350 degrees fahrenheit.

Spray a 9 x 13 inch baking dish with non-stick spray and set aside.

In a medium sauce pan, combine sauce and meatballs and heat over medium-low for about 10 minutes, until warmed through.

Cut your 12 Hawaiian rolls in half, and place the bottom half of the rolls into the prepared baking dish.

Layer about half of the mozzarella cheese on the bottom rolls.

Remove meatballs from the heat and place one meatball onto each roll, and drizzle about 2 Tablespoons of sauce over each meatball.

Sprinkle the remaining mozzarella cheese over top of the meatballs.

Add more sauce over the meatballs as desired. Don't drench them - we want sauce but not soggy sliders. Save any leftover sauce for dipping.

Place the top buns into the sliders.

In a small bowl, stir together olive oil, parmesan cheese, and Italian seasoning. Brush the oil mixture over top of the sliders.

Bake for 20 minutes, tenting the sliders with foil for the last half of the baking time to avoid the tops from getting too brown..

Use a knife to cut the rolls apart and serve.
