Prepare the Rolls: Slice the rolls in half horizontally without separating them and place the bottom half on a lightly greased baking sheet.
12 Hawaiian sweet rolls
Build the Base Layers: Lay the provolone over the bottom rolls, then add the pepperoni, salami, and ham in even layers so every slider actually gets the good stuff.
6 slices provolone cheese, 9 slices pepperoni, 9 slices salami, 9 slices ham
Add the Tangy Crunch: Spread the banana pepper rings and sliced red onion over the meat, keeping them evenly distributed.
½ cup banana pepper rings, ½ medium red onion
Finish the Stack: Place the mozzarella slices on top, then set the top half of the rolls back in place.
6 slices mozzarella cheese
Mix the Butter Topping: Stir the melted butter, Italian seasoning, and garlic powder together in a small bowl until combined.
4 tablespoons butter, ½ teaspoon Italian seasoning, ½ teaspoon garlic powder
Make-Ahead Tip: If you’re assembling these ahead of time, wait to brush on the butter mixture until right before baking so the rolls don’t turn soggy.
Brush and Bake: Brush the butter mixture all over the tops of the rolls, then bake at 350°F for 10–15 minutes, until the cheese is melted and the tops are lightly golden.
Serve: Sprinkle Parmesan over the sliders, slice them apart, and serve warm with marinara on the side for dipping.
2 tablespoons grated Parmesan cheese, ½ cup marinara sauce
