Slice the rolls in half lengthwise. Place the bottom half in a 9 x 13-inch baking dish. Spread the chicken evenly on top, followed by the marinara, cheese, and top with the remaining rolls.
In a small bowl mix the melted butter with the garlic powder, Italian seasoning, and Parmesan. Brush the tops of the rolls with the butter mixture.
Bake for 15 minutes, or until the cheese is melted and the bread is golden brown. Slice into individual sliders and ENJOY!
