puupia: I think that when you look at the selection of toppings, it is clear that it is the American pizza what should be considered here. You can hardly get any other salami than pepperoni in the U.S., while here in Europe it is quite common to use quite a variety of salamis. Also the cheeses listed in the poll are rarely used in continental Europe (except for mozzarella, of course). We don't use provolone, cheddar, or Colby (which is actually a cheddar too). Instead, edam is very popular, as well as a number of blue-veined chesses. Then the bacon – the European bacon is not the same as the American one. And so on and so forth. You're right about the chicken, turkey, and I would also add beef. To sum it up, American pizza is simply different from European pizza. And I have different favorite toppings for each of them. :)
