Philly Cheesesteak Cheese Bread

 Preheat oven to 375°F.
 In a small bowl, toss the shaved steak with oil, half the salt, and half the pepper.
 Heat a frying pan over medium heat, add steak, and cook for 2 minutes without stirring. Add Worcestershire sauce, stir well, and continue to cook until no longer pink. Remove meat from the pan.
 Melt butter in the same pan, add green bell pepper, onion, and mushrooms. Cook until softened and beginning to brown, about 5-8 minutes. Remove from heat.
 Line a large baking sheet with foil. Place bread halves on the baking sheet, cut side up.
 Spread mayonnaise on both halves of the bread. Layer half the provolone cheese on the bread, then top with steak and veggies, followed by the remaining cheese.
 Bake for 15 minutes until cheese is melted and starting to brown at the edges.
 Cut into smaller servings and serve warm.

 Notes:

 This sandwich is perfect for a hearty meal and can be served with a side salad.
 Customize the toppings according to your preferences or dietary needs.
 If you’re not a fan of mayonnaise, try brushing the bread with melted butter instead.
