I'm sure if you don't put too much cheese or fatty meats like chorizo (sp?), salami etc. on, a pizza should be reasonably good for you. Personally though, I come from the school of pizza making that tends to add whatever is on hand and might taste alright - usually along the lines of zucchini, peppers, olives, mushrooms, salami (and cheese and tomato paste of course). You can really put anything on 'em though. My favourite bar/restaurant at home does and amazing salmon, cream cheese an sweet chili pizza (and some other pretty darned good ones).

Arrgh. Drool. Is it lunchtime yet?
