Making Ground Beef Philly Cheesesteaks is a simple process. Follow these easy steps:

1. Heat Olive Oil: In a large skillet, heat the olive oil over medium heat.
2. Cook Vegetables: Add the sliced onions and bell peppers. Sauté for about 5-7 minutes until they are soft and translucent.
3. Brown the Beef: Add the ground beef to the skillet with the vegetables. Cook until browned, breaking it apart with a spatula.
4. Season the Mixture: Stir in garlic powder, salt, and pepper. Mix well to combine the flavors.
5. Melt the Cheese: Reduce the heat to low. Place slices of cheese on top of the beef mixture. Cover the skillet with a lid for a couple of minutes to allow the cheese to melt.
6. Prepare the Rolls: While the cheese is melting, slice the hoagie rolls open lengthwise without cutting all the way through.
7. Fill the Rolls: Once the cheese has melted, use a spatula to scoop the beef mixture into the hoagie rolls.
8. Serve Immediately: Serve the cheesesteaks hot, optionally topped with your favorite condiments or hot sauce.
