Preheat oven to 375°F. Spray a 9x13 baking pan with olive oil cooking spray. Set aside.

To make the garlic butter, add melted butter, grated garlic, Italian seasoning, salt, and black pepper to a small bowl. Whisk to combine. Set aside.

Place the dinner rolls into the prepared baking pan. Cut out a 1.5-inch well in the center of each roll with a small, sharp paring knife. Be careful not to cut too deep into the roll.

Using a pastry brush, brush the garlic butter into the wells and around the tops of all the dinner rolls.

Spoon 1 to 1.5 tablespoons of marinara sauce into each well (leave some sauce for later).

Add a meatball to each sauce-filled well and top with the remaining marinara sauce.

Sprinkle grated parmesan and shredded mozzarella over the entire surface of the rolls and meatballs.

Bake for 20-25 minutes or until cheese is melted and bubbly.

Sprinkle with chopped parsley and serve warm.
