Preheat your oven to 350 degrees Fahrenheit.
Spray a 9x13 inch pan with non-stick spray and set aside.
In a medium sauce pan, combine pasta 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 9x13 inch pan.
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 tbsp. Of pasta sauce over each meatball.
Sprinkle the remaining mozzarella cheese over top of the saucy meatballs.
Drizzle a bit more pasta sauce over the meatballs. You won’t use the entire 2 cups, we want sauce but not soggy sliders, so you can just discard any leftover sauce.
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 over browning the tops.
Use a knife to cut the rolls apart and serve!
