Follow these steps to create your Ultimate Philly Cheesesteak Pizza:

1. Preheat the Oven: Preheat your oven to 475°F (245°C).
2. Prepare the Steak: In a skillet over medium-high heat, add olive oil. Once hot, add the thinly sliced steak. Season with salt, pepper, and Worcestershire sauce. Sauté for about 3-4 minutes until browned but not fully cooked. Remove from heat and set aside.
3. Sauté Vegetables: In the same skillet, add the sliced onion, bell pepper, and garlic. Sauté for 3-5 minutes until softened. Remove from heat.
4. Assemble the Pizza: Roll out your pizza crust on a floured surface. Place it on a pizza stone or baking sheet. Spread a layer of the sautéed vegetables evenly over the crust.
5. Add the Steak: Evenly distribute the partially cooked steak over the vegetables.
6. Add the Cheese: Sprinkle the provolone and mozzarella cheese generously over the top.
7. Bake: Place the pizza in the preheated oven and bake for 12-15 minutes, or until the crust is golden brown and the cheese is bubbly.
8. Garnish: Remove the pizza from the oven and let it cool for a few minutes. Garnish with chopped parsley if desired.
9. Slice and Serve: Use a pizza cutter to slice the pizza into wedges.
