Cut bread in half lengthwise.

Bake at 450°F for 10-15 minutes or until cheese is melted.
Cook’s note: This recipe serves 8 so you may have enough for lunch the next day. To reheat, wrap in foil and heat in a 350° F oven for 10-15 minutes or until hot. This results in French bread that is soft. If you prefer crispy bread, place the loaf on a baking sheet and bake 10-15 minutes or until hot.
