Since pizzas can include a very wide variety of toppings, one particular type of pizza party allows the guests to create their own custom-made pizza, using a selection of ingredients from among the toppings provided by the party's host.
When a pizza party does not include any custom-made pizzas, and the particular preferences of the guests are unknown, it is common to include at least one plain cheese-only and/or vegetable-only pizza for people who are averse to meats or other available toppings.
