A pizza in the form of a Christmas tree will be so much fun to have on the Christmas day. The basic of this pizza is to have the pizza dough cut in the form of a tree. The topping depend totally on you but for your idea here are four pictures that have used different things to show the parts of a Christmas tree for example pepperonis for ornaments, olives, ketchup or onions for the garlands. For your convenience we have found the recipies of all the four pizzas and you can get them by following these links 1 , 2 , 3 and 4. Bon appetite!
