With the pizza, I would seriously recommend adding up your own ingredients, as it'll vary widely depending on what you can get in different countries (I'm acutely aware of this as I'm from Australia and there's stuff that I can't get here- England- or that I won't be able to get when I go back to Australia). I've used that recipe 6 times now and the calories varied between 270 and 370 calories per pizza (my variation- ham, olives, tomato sauce, sundried tomato, mushroom, onion, fresh basil, garlic, cheese- is lower calorie than the one I made for my boyfriend- chicken, ham, onion, mushroom, garlic, cheese, barbecue sauce). The pizza is probably potentially "dangerous" as it contains ingredients that are high calorie density (cheese is a killer- even with "diet" cheese), so you need to exercise caution there.
But mushroom is a good low calorie addition- you get 29 grams, a little over an ounce, for 6.4 calories. (I just looked that up on my calorie calculator)
