01 - Heat 1 tbsp of olive oil in a large skillet over medium-high heat. Add the sliced onions and green peppers, sautéing for 4-5 minutes until softened and lightly caramelized. Transfer to a plate and set aside.
02 - Add the remaining 1 tbsp olive oil to the same skillet. Add the ground beef, breaking it apart with a spatula into small crumbles. Cook for 6-8 minutes until thoroughly browned and no pink remains. Drain excess fat if needed.
03 - Stir in the minced garlic, Worcestershire sauce, salt, and black pepper. Cook for 1-2 minutes until fragrant. Return the sautéed peppers and onions to the skillet and toss everything together to combine evenly.
04 - Reduce heat to low. Arrange the provolone cheese slices over the beef mixture in an even layer. Cover the skillet and let sit for about 2 minutes until the cheese is fully melted.
05 - While the cheese melts, place the split hoagie rolls under a broiler or in a toaster oven. Toast until golden brown and lightly crisp, about 1-2 minutes.
06 - Spoon the cheesy beef and vegetable mixture evenly onto each toasted hoagie roll. Serve immediately while hot.
