Mozzarella cheese cut into strips or use string cheese pulled into strips
Sliced black olives
Toast the bread. Spread on a layer of pizza sauce and arrange the cheese so that it resembles mummy bandages. Hide the black olive eyes so that they peak out from under the cheese bandages. Pop them under the broiler until the cheese melts slightly or serve just as they are.
