Philly Cheesesteak Sliders

Ingredients

• Olive oil (2 tablespoons)
• Salt (to taste)
• Black pepper (to taste)
• Dijon mustard (1 tablespoon)
• Mayonnaise (2 tablespoons)
• Slider buns (12 (small-sized))
• Provolone cheese (12 slices)
• Onion (1 large, thinly sliced)
• Bell peppers (2 (1 red, 1 green), thinly sliced)
• Steak (ribeye or flank steak) (1 pound, thinly sliced against the grain)

Instructions

1. Preheat the oven to 350°F (175°C).
2. In a large skillet, heat the olive oil over medium heat.
3. Add the sliced onions and bell peppers to the skillet. Sauté until they are soft and slightly caramelized, about 8-10 minutes. Season with salt and pepper to taste.
4. Push the sautéed onions and peppers to one side of the skillet. Add the thinly sliced steak to the other side. Season the steak with salt and pepper, cooking until browned and cooked through, about 3-4 minutes per side.
5. Slice the slider buns in half horizontally and arrange the bottom halves in a baking dish.
6. Spread a layer of mayonnaise on the bottom halves of the slider buns, followed by a drizzle of Dijon mustard for an extra punch of flavor.
7. Layer the cooked steak evenly on top of the mayonnaise.
8. Top the steak with the sautéed onions and peppers.
9. Place a slice of provolone cheese on top of the onion and pepper mixture, ensuring it covers the filling well.
10. Cover with the top halves of the slider buns.
11. Cover the baking dish with foil and bake in the preheated oven for 10-12 minutes, or until the cheese is melted and the sliders are heated through.
12. Remove from the oven, let cool slightly, and serve warm. Enjoy the delicious melty goodness!
