Follow these easy-to-follow steps to create your Easy Philly Cheese Steak and enjoy a delightful meal:

1. Heat Olive Oil: In a large skillet, heat the olive oil over medium-high heat.
2. Sauté Vegetables: Add onion and bell pepper to the skillet, cooking until softened and slightly caramelized, about 5-7 minutes.
3. Cook Steak: Push the vegetables to the side and add the thinly sliced steak to the pan. Season with salt and pepper. Cook until the meat is browned and cooked to your preference, about 3-5 minutes.
4. Combine Ingredients: Mix the cooked vegetables and steak together in the skillet, combining evenly.
5. Melt Cheese: Reduce heat to low, top with provolone cheese (or drizzle with Cheez Whiz), and cover the pan. Allow the cheese to melt for 1-2 minutes.
6. Toast Rolls *(Optional)*: While the cheese melts, you can toast the hoagie rolls in an oven or on a griddle if desired.
7. Assemble Sandwiches: Remove the skillet from heat. Scoop the cheesy steak mixture generously into each hoagie roll.
8. Serve Immediately: As soon as assembled, these sandwiches are best enjoyed piping hot!

By following these instructions, you can create a mouth-watering Easy Philly Cheese Steak that tantalizes your taste buds.
