Preheat the oven to 350°F/180°C, and grease a 9x9 or 7x11 inch baking pan/sheet (if you don’t have either, then use 9x13).
In a small bowl, combine melted butter and Italian seasoning.
Slice the rolls in half using serrated knife to separate the tops from the bottoms.
Place the bottom of the rolls in the pan. Layer half of the cheese, all of the pizza sauce, and then layer the pepperoni. Top with the remaining cheese. Cover with the top buns.
Brush the herb butter mixture over the tops, cover with foil and bake for 15 minutes. Remove the foil, and bake uncovered for 10 more minutes or until done/golden brown. Watch the sliders so they don’t burn.
If you can't find Hawaiian rolls, you can use dinner rolls instead. Look for the type of rolls that are already cooked and still stuck together.
Leave out the pepperoni if you'd like, or add other cooked pizza toppings like mushrooms, sausage, or sauteed onions.
To Store: These sliders are best enjoyed right after baking them, but leftovers can be saved in the fridge for 2-3 days if needed. Reheat them in the oven or air fryer just until warm.
