Quilt pizza is an exciting and easy way to get all your guests involved. It becomes an activity in and of itself. First, get a ton of toppings: vegetables, meats, even some pineapple--whatever you like--and pile each one into separate bowls. Next, buy some refrigerated pizza dough from the grocery store or your local pizzeria and stretch it over the backside of a baking sheet. Then place everything out on a table and let the kids (or adults) go crazy. Everyone gets a square on the dough to design his or her own patch of pizza.
