Making Ground Beef Philly Cheesesteaks is a simple process. Just follow these steps:

1. Heat the Pan: In a large skillet, heat a tablespoon of olive oil over medium heat.
2. Cook the Vegetables: Add the sliced onions and bell peppers (if using) to the skillet. Sauté for about 5 minutes until they become soft and slightly caramelized.
3. Add Garlic: Stir in the minced garlic and cook for an additional minute, stirring frequently to avoid burning.
4. Brown the Beef: Push the vegetables to the side of the skillet, then add the ground beef. Cook until browned, breaking it apart with a spatula, about 5-7 minutes.
5. Season the Mixture: Once the beef is browned, add Worcestershire sauce, salt, black pepper, and paprika. Mix everything together and let it cook for another minute.
6. Melt the Cheese: Reduce the heat to low. Lay the slices of cheese over the beef mixture, covering it evenly. Cover the skillet with a lid to help the cheese melt, about 2-3 minutes.
7. Prepare the Rolls: While the cheese is melting, slice the hoagie rolls lengthwise without cutting all the way through.
8. Fill the Rolls: Once the cheese is melted, use a spatula to scoop the beef and vegetable mixture into the rolls.
9. Serve Immediately: Enjoy your Ground Beef Philly Cheesesteaks hot, optionally garnished with additional toppings like hot sauce or pickles.
