Cheesy Garlic Burgers

Directions

1. Preheat oven to 375°. In a large bowl, combine beef and 1 teaspoon garlic powder. Shape into six thin patties. In a large nonstick skillet, cook patties in batches over medium heat until no longer pink, 4-5 minutes on each side.
2. Meanwhile, cut bread in half lengthwise. Combine butter and remaining 1 teaspoon garlic powder; spread over cut sides of bread. On the bottom half, layer provolone cheese, beef patties and mozzarella cheese. Replace bread top. Wrap sandwich in foil. Place on a baking sheet.
3. Bake until cheese is melted and sandwich is heated through, 5-10 minutes. Cut loaf between each patty. Serve with spaghetti sauce for dipping.
