In a large skillet over medium heat, add the ground beef. Cook until browned, breaking it apart with a spatula, about 5-7 minutes.

Add the chopped onion, green bell pepper, and minced garlic to the skillet. Cook until the vegetables are soft, about 5 minutes.

Stir in the Worcestershire sauce, salt, and pepper. Mix well and cook for an additional 2 minutes.

Preheat your oven to 350°F (175°C). Slice the hoagie rolls in half and place them on a baking sheet.

Spoon the ground beef and vegetable mixture evenly into each hoagie roll.

Top each filled roll with 2 slices of provolone cheese or a generous amount of Cheez Whiz.

Place the baking sheet in the preheated oven and bake for about 5-7 minutes, until the cheese is melted and bubbly.

Remove from the oven, let cool slightly, and serve hot.
