1 cup (113g) mozzarella cheese, grated

1 cup (113g) sharp cheddar cheese, grated

parsley, chopped for garnish

Instructions:
Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.

Slice the bread in half lengthwise. Place both halves of the bread on the baking sheet, cut side up.

Combine the butter and garlic salt in a small bowl. Spread the butter mixture on the cut sides of the bread. Set the mixture aside while you make the Sloppy Joe filling.

Sloppy Joe:

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

Assembly:

Spread the sloppy joe mixture over both sides of the breads and top with the mozzarella and cheddar cheese. Bake for 12-14 minutes or until golden brown.
