Creating delicious Philly Cheesesteak Sliders is simple! Just follow these steps for perfect results:

1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Sauté the Vegetables: In a large skillet, heat the olive oil over medium heat. Add the sliced onions and bell peppers. Sauté until they are soft, about 5-7 minutes. Season with salt and pepper.
3. Cook the Beef: Add the thinly sliced beef to the skillet. Pour in Worcestershire sauce and cook until the beef is browned and cooked through, about 4-5 minutes.
4. Prepare Slider Buns: While the beef cooks, slice the slider buns in half without separating them completely. Place the bottom half in a baking dish.
5. Add the Beef Mixture: Once the beef is cooked, evenly spread the beef and vegetable mixture over the bottom half of the slider buns.
6. Layer the Cheese: Place slices of provolone cheese on top of the beef mixture, covering it completely.
7. Add the Top Buns: Place the top half of the slider buns over the cheese layer.
8. Brush with Butter: Brush the melted butter over the top of the buns for added flavor and a golden finish.
9. Bake: Place the baking dish in the preheated oven and bake for 15-20 minutes, or until the cheese is melted and the buns are slightly toasted.
10. Slice and Serve: Remove from the oven, slice the sliders, and serve warm.

These straightforward steps will help you create mouth-watering Philly Cheesesteak Sliders that everyone will love!
