Creating these amazing Hot Italian Sub Sliders is simple! Follow these steps for perfect results:

1. Preheat the Oven: Start by preheating your oven to 375°F (190°C).
2. Prepare Baking Dish: Grease a 9×13 inch baking dish with non-stick spray or a little oil to prevent sticking.
3. Slice Buns: Cut the slider buns in half, creating a top and bottom half, and place the bottom halves in the baking dish.
4. Spread Marinara Sauce: Evenly spread the marinara sauce over the bottom halves of the buns.
5. Layer the Meats: Start layering the salami, ham, and pepperoni generously over the marinara sauce.
6. Add Cheese: Place the provolone cheese slices over the meats.
7. Add Banana Peppers: Sprinkle the sliced banana peppers on top of the cheese.
8. Season: Sprinkle Italian seasoning over the entire layered slider.
9. Close the Sliders: Place the top halves of the buns on each slider, pressing down gently.
10. Prepare Butter Mixture: In a small bowl, mix the melted butter with garlic powder and salt.
11. Brush the Sliders: Brush the butter mixture over the top of the buns for extra flavor and crispiness.
12. Bake Sliders: Cover the baking dish with aluminum foil and bake in the preheated oven for 10-15 minutes.
13. Remove Foil: After 15 minutes, uncover the sliders and bake for an additional 5-10 minutes, or until the tops are golden brown and crispy.
14. Garnish & Serve: Optionally, sprinkle freshly chopped parsley on top for garnish before serving.
