Preheat your oven to 350˚F, ensuring it's hot enough to melt the cheese and crisp up the slider tops perfectly.
Cut the hawaiian rolls horizontally, creating two halves for each roll, and lay them bottom side up in a baking dish.
Start layering by placing provolone cheese on each half of the rolls, followed by chicken ham, turkey pepperoni, and thinly sliced turkey.
Place back on top of each roll half, then blend together butter, grated parmesan, garlic powder, and salt; spread generously over the tops.
Bake in the oven for about 15-20 minutes until cheese is melted and slider tops are golden brown.
While sliders are baking, whisk together mayonnaise, apple cider vinegar, Italian seasoning, salt, pepper, and garlic powder; fold in shredded lettuce, diced tomatoes, and pepperoncini peppers before serving on top of baked sliders once done.
