Preheat oven to 350°
Line a roasting pan with foil and grease with cooking spray.
Mix all of the ingredients together in a large mixing bowl until combined. Do not overmix!
Form the meat mixture into about 8 fist sized loaves.
Make a small indentation into each loaf and press a folded slice of American cheese into the center. Fold the meat over the cheese, being careful to fully cover the cheese.
Mix the 1 cup of ketchup with the ½ cup of brown sugar in a small bowl. Top each loaf with the sauce mixture.
Bake on roasting pan for 45 mins to 1 hour, or until internal temperature reaches 165°.
