01 - Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the sliced onions and green bell pepper and sauté for 4 to 5 minutes until softened and lightly caramelized. Transfer to a plate and set aside.
02 - Add the remaining 1 tablespoon of olive oil to the same skillet. Add the ground beef, breaking it apart with a spatula, and cook for 6 to 8 minutes until evenly browned and crumbly. Drain excess fat if needed.
03 - Stir in the minced garlic, Worcestershire sauce, salt, and black pepper. Cook for 1 to 2 minutes until fragrant. Return the sautéed peppers and onions to the skillet and toss everything together.
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 - Place the split hoagie rolls under a broiler or in a toaster oven and toast until golden and crisp on the edges.
06 - Spoon the cheesy beef and vegetable mixture evenly onto the toasted rolls. Serve immediately while hot.
