Let stand 15 minutes. Heat 20 seconds longer. Cut bread in half horizontally. Spoon margarine onto each half of bread, avoiding garlic chunks. Parsley may be lightly sprinkled onto margarine.
Close bread halves together and wrap in foil.
Bake for 20 minutes in 350' oven. Lay bread open on foil and place desired amount of soy mozzarella cheese on each bread half. Toast under broiler until lightly browned.
