Found this recipe on many sites on web....but changed a few things! Old fashioned Sugar Cookie recipe on bottom (browned up nicely as pan pizza crust!), 2 pkgs cream cheese/sugar/vanilla, chopped strawberries (for tomatoes) and covered with marzipan olives, pepperoni, mushrooms and green peppers. Real pineapples were used, also. Yellow and white sugar paste was grated on top to give sense of cheese. Custom made pizza box finished the look to celebrate National Pi Day for high school math class!
