Garlic Bread in a Bag

Preheat the oven to 450°. In a small bowl, blend the garlic with the butter. Spread each bread half with 1 tablespoon of the garlic butter and sprinkle with 1 tablespoon of the Parmesan. Sandwich the bread halves together and put the loaf in a paper bag. Fold the top closed and bake in the center of the oven for about 8 minutes, or until the bag darkens slightly and the bread feels crisp when pressed through the bag
