Creating Hot Italian Sub Sliders is simple if you follow these steps:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C).
2. Prepare the Base: Lightly grease a baking dish or line it with parchment paper for easier cleanup.
3. Assemble the Buns: Slice the slider buns in half horizontally. Place the bottom halves in the prepared dish.
4. Layer the Meats: Evenly distribute salami, pepperoni, and ham over the bottom halves of the buns.
5. Add Cheese and Peppers: Layer the provolone cheese and sliced banana peppers on top of the meats.
6. Drizzle Dressing: Pour the Italian dressing evenly over the cheese and peppers for added flavor.
7. Top the Sliders: Place the top halves of the slider buns onto the fillings.
8. Mix Butter and Spices: In a small bowl, combine melted butter, garlic powder, Italian seasoning, and optional red pepper flakes.
9. Brush the Tops: Brush the butter mixture generously over the tops of the slider buns for extra flavor and a golden finish.
10. Bake: Place the dish in the preheated oven and bake for 25-30 minutes, or until the tops are golden brown and the cheese is melted.
11. Prepare for Serving: Once baked, remove from the oven and allow to cool for a few minutes before slicing into individual sliders.
12. Garnish: Sprinkle chopped fresh parsley over the sliders for a touch of color and flavor.
