330 calories for half the pizza! Thats a serving!Cauliflower crust margherita pizza sounds low cal to me, guess it depends on how much you eat!
I think just the fact that you are thinking about so clearly will lead you to good choices. Keep it up, and let us know where it ended.
I feel like im cheating though. I keep thinking about this article i read about a guy who ate nothing but twinkies or something and still lost weight because of the calorie deficit. I dont want to fall back into old habits this soon...or at all for that matter.
