To make the garlic bread, combine the softened unsalted butter, minced garlic, chopped parsley, and salt in a small bowl. Spread this mixture evenly over the cut sides of the halved hoagie rolls. Place the rolls on a baking sheet and toast in an oven preheated to 375°F (190°C) for 5-7 minutes, or until golden brown. If using, sprinkle grated Parmesan cheese before toasting for extra flavor.

Ensure the butter is truly softened for easy spreading. Do not over-toast, as the bread will be baked again.📌

For the sloppy joe filling, heat a large skillet over medium-high heat. Add the diced onion and diced bell pepper, and sauté until they are soft, about 5-7 minutes. Add the 2 cloves of minced garlic and cook for another minute until fragrant. Add the ground beef to the skillet, breaking it apart with a spoon as it cooks. Cook until the ground beef is completely browned, then drain any excess grease.

Draining excess grease prevents the filling from becoming too oily and ensures a richer flavor.📌

Once the ground beef is browned and drained, stir in the marinara sauce, tomato paste, Italian seasoning, salt, and black pepper. If desired, add red pepper flakes for a touch of heat. Bring the mixture to a simmer and cook for 5-10 minutes, stirring occasionally, until the sauce has thickened to your desired consistency.

Allowing the mixture to simmer helps the flavors meld together and the sauce to reduce.📌

Carefully spoon the prepared sloppy joe filling onto each toasted hoagie roll half. Generously top each with the shredded mozzarella cheese.

Ensure an even layer of filling and cheese for consistent flavor in every bite.📌

Return the assembled sloppy joes to the oven and bake for another 5 minutes, or until the cheese is completely melted and bubbly, and slightly golden.

Watch the cheese closely to prevent it from burning. The goal is gooey, melted cheese.📌
