• Preheat oven to 350°F*. Line a baking sheet with parchment paper.
• Slice the loaf of bread lengthwise into two halves. Place both halves of the bread onto the lined baking sheet, cut side up.
• In a small bowl, combine the butter and garlic salt. Spread the butter mixture over the cut sides of the bread. Set aside while you make the sloppy joe filling.

Sloppy Joe

• In a medium nonstick skillet over medium heat, cook the ground beef and onions until the beef is no longer pink (8-10 minutes). Drain grease. Stir in the garlic powder, mustard, ketchup, salt, pepper, and water, mixing until combined.

Assembly

• Divide the sloppy joe mixture between both sides of the loaves and top with the mozzarella and cheddar cheese. Bake for 12-14 minutes or until golden brown.
• Cut into pieces and serve with parsley for garnish.
