Pizza is universal. You can get it anywhere in the modern world. You can get it in the future, in space, and in other timelines. You can also make a good case for getting it in historical time periods. Even if it's not historically known in any given time and place, some enterprising person can easily invent it, given nothing more than some grain, some dairy, and some of whatever other food is around.
Try inventing it next time you're playing in a period where it would otherwise be unknown. You'll quickly become rich and famous! Or can at least make that argument to your GM.
