Cut both sheets of rolls in half horizontally to create top and bottom buns. Place bottoms into two 9x13 baking pans.
Sprinkle 3/4 cup mozzarella on each bottom half of rolls. Layer 12 slices of ham on top of cheese. Top with 1/2 can of Dei Fratelli Pizza Sauce and another 3/4 cup mozzarella cheese on each sheet. Cover with tops of rolls.
Melt butter in a small bowl. Combine with Italian seasoning, garlic, and parmesan cheese. Brush tops of buns evenly with butter mixture.
Place in oven and bake for 20 minutes.
Try them with pineapple slices for a true Hawaiian pizza, or make them your own by filling with different pizza toppings!
