Preheat your oven to 350°F (175°C). Gather your ingredients while the oven heats up.

Slice Hawaiian rolls in half horizontally and place bottom halves in a greased baking dish, cut side up.

Layer turkey ham, salami, and pepperoni across the bottom half of the rolls.

Place slices of provolone cheese on top of the layers of meat.

Place the top halves of the rolls back onto the filled bottom halves and press down slightly.

In a small bowl, combine melted butter, garlic powder, Italian seasoning, and grated parmesan cheese. Brush over the tops of the rolls.

Cover the baking dish with foil and bake for 15 minutes. Remove foil and continue baking for an additional 5 minutes.

While baking, prepare topping by combining lettuce, onion, banana peppers, mayonnaise, olive oil, red wine vinegar, and black pepper.

After baking, let sliders cool for a few minutes. Spoon the lettuce mixture inside each slider.

Slice the sliders into individual portions and serve warm.
