Heat a large skillet over medium-high heat and drizzle a bit of olive oil to coat the bottom. Once the oil shimmers, add the ground beef. Use a spatula to break the beef into smaller pieces as it cooks. Season generously with salt, pepper, and smoked paprika. Cook for approximately 5-7 minutes, or until the beef is nicely browned, draining any excess fat if necessary.
Push the browned beef to one side of the skillet, creating space. Add the thinly sliced onion, green bell pepper, and red bell pepper to the opposite side of the skillet. Sauté the vegetables for about 3-5 minutes, until they soften. Once tender, stir them into the beef mixture. Then, add the minced garlic and Worcestershire sauce, mixing everything well. Cook for an additional 2 minutes to allow the flavors to meld and the garlic to become fragrant.
Reduce the heat to medium-low. Arrange the slices of provolone cheese over the beef and vegetable mixture. Let it cook gently for about 2-3 minutes until the cheese is melted and gooey. Consider covering the skillet with a lid for quicker results.
While the cheese is melting, take the hoagie rolls and lightly toast them in a separate pan with a touch of olive oil or under the broiler for a couple of minutes until they are golden brown and crispy.
Once the cheese has melted, carefully divide the savory beef and vegetable mixture among the toasted hoagie rolls, ensuring each roll is generously filled.
Sprinkle chopped parsley over the filled sandwiches and serve immediately to enjoy the melty, cheesy goodness while they’re hot and fresh.
Notes
For quicker cheese melting, cover the skillet with a lid.
