Can't say I've ever bothered to look up pizza in a dictionary before, but here we are. dictionary.com has this to say about the word pizza: a flat, open-faced baked pie of Italian origin, consisting of a thin layer of bread dough topped with spiced tomato sauce and cheese, often garnished with anchovies, sausage slices, mushrooms, etc. And the dictionary that comes with MacOS claims the origin of the word pizza is Italian, litterally 'pie'. <shrug>
