In a large skillet over medium-high heat, brown 1 pound of ground beef or turkey for about 5-7 minutes, breaking it up with a spatula until fully cooked. Drain any excess fat and transfer the meat to a bowl.

In the same skillet, add a finely chopped large yellow onion and a medium green bell pepper. Sauté over medium heat for about 3-5 minutes until softened. Add 2 minced garlic cloves and stir for an additional minute.

Return the cooked meat to the skillet and add in 1 cup of tomato sauce, 1/4 cup of ketchup, 1 tablespoon of light brown sugar, 1 tablespoon of Worcestershire sauce, 1 tablespoon of yellow mustard, and 1 tablespoon of apple cider vinegar. Stir together over medium heat for about 2-3 minutes.

Reduce heat to low and let the mixture simmer for 20-30 minutes, allowing the sauce to thicken slightly. Stir occasionally.

Mix 4 tablespoons of softened unsalted butter with 2 minced garlic cloves, 1 tablespoon of chopped parsley, and a pinch of salt. Spread this garlic butter mixture on one side of each slice of 8 thick-cut bread.

On half of the prepared bread slices (garlic butter side up), layer 1/2 cup of shredded cheese, followed by an ample scoop of the hot sloppy joe filling. Top with another slice of bread, butter side up.

Bake the melts in a preheated oven at 375°F for 10-15 minutes, or until the bread is golden brown and crispy. Alternatively, cook them in a skillet over medium heat for about 4-5 minutes on each side until toasted and the cheese has melted.

Once cooked, let the Cheesy Garlic Bread Sloppy Joe Melts rest for a couple of minutes, then slice them in half for easier handling.
