Follow these simple steps to create your Ground Beef Philly Cheesesteaks:

1. Heat Oil: In a large skillet, heat olive oil over medium heat.
2. Sauté Vegetables: Add the sliced onions and green bell peppers to the skillet. Sauté for about 5 minutes until soft.
3. Add Garlic: Stir in the minced garlic and cook for another minute until fragrant. Remove the vegetables and set them aside.
4. Cook Ground Beef: In the same skillet, add the ground beef. Cook, breaking it apart, until browned and fully cooked (about 5-7 minutes).
5. Season: Drain excess fat if needed. Stir in Worcestershire sauce, and season with salt and pepper to taste.
6. Combine: Add the sautéed onions and peppers back into the skillet with the ground beef. Mix thoroughly.
7. Melt Cheese: Place cheese slices on top of the beef mixture, covering it. Allow the cheese to melt for about 2-3 minutes.
8. Prepare Rolls: While the cheese is melting, cut the hoagie rolls lengthwise, ensuring not to cut all the way through.
9. Assemble: Using a spatula, scoop the cheesesteak mixture into each hoagie roll.
10. Serve: Optionally, toast the assembled sandwiches in a toaster oven or skillet until golden brown.

By following these steps, you’ll create incredibly flavorful Ground Beef Philly Cheesesteaks that are sure to impress!
