Everyone loves a pizza party! But this is no elementary school birthday party; this is a full-out feast of grown-up pies, best enjoyed with everyone pitching in for pizza creation together. Invite eight to ten of your friends over, open a few bottles of wine, and spend the evening assembling topping and baking your pies — just be sure to make a lot of dough the night before. Split up the prep work on the day of dinner by assigning each guest to bring their own favorite pizza toppings. This is a meal to eat in stages, as each new pizza comes out of the oven, cut into small slices so everyone can have a taste.
