Prepare the Sloppy Joe Filling:

1. Cook the Ground Beef: Heat a large skillet over medium heat. Add the ground beef and cook until browned, breaking it up with a wooden spoon, about 5-7 minutes. Drain any excess fat.
2. Add Aromatics: Stir in the diced onion and minced garlic. Cook for another 2-3 minutes, or until the onion becomes translucent and fragrant.
3. Incorporate Tomatoes: Add the tomato sauce, tomato paste, oregano, basil, crushed red pepper flakes, Worcestershire sauce, salt, and pepper. Stir to combine.
4. Simmer: Reduce the heat to low and simmer for 10 minutes, allowing the flavors to meld. Stir occasionally.
5. Add Cheese: Stir in ½ cup of shredded mozzarella until melted and incorporated.

Prepare the Garlic Bread:

6. Preheat the Broiler: Set your oven to broil and line a baking sheet with parchment paper.
7. Make the Garlic Butter: In a small bowl, mix the softened butter, minced garlic, parsley, and Parmesan cheese until well combined.
8. Spread on Bread: Slice the sandwich rolls or bread in half and spread the garlic butter mixture evenly on each piece.
9. Toast: Place the bread on the prepared baking sheet and broil for 1-2 minutes, or until golden and lightly crispy. Watch carefully to avoid burning.
