Ready to get cooking? Follow these simple steps to whip up your own batch of Hot Italian Sub Sliders:

1. Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper for easy cleanup.
2. Slice the slider buns in half horizontally, keeping them attached to each other. Place the bottom halves on the prepared baking sheet.
3. In a small bowl, mix together the mayonnaise and Dijon mustard. Spread this mixture evenly over the bottom halves of the buns.
4. Layer the provolone cheese, ham, salami, and pepperoni over the mayonnaise mixture. Top with banana pepper rings and black olives, if using.
5. Place the top halves of the buns over the layers of meat and cheese.
6. In another small bowl, combine the melted butter, Italian seasoning, and garlic powder. Brush this mixture generously over the tops of the buns.
7. Cover the sliders loosely with aluminum foil and bake in the preheated oven for 15 minutes. This helps the cheese melt without over-browning the tops.
8. Remove the foil and bake for an additional 5 minutes, or until the tops are golden brown and the cheese is bubbly.
9. Let the sliders cool for a few minutes before slicing and serving. Enjoy the warm, gooey goodness!

These sliders remind me of the many times I helped my abuela in the kitchen, learning the art of layering flavors and the joy of sharing a meal with loved ones.
