pizza is my food too. not sweets. not salts. just freakin pizza.
i have several ways that i deal with this though. i am a calorie counter all the way, so i just have figured out some low to mid range calorie pizza options. first and formost, (mentioned before) the LC Pizzas. the spinach and mushroom (310cal) and the brickoven gormet mushroom (290). then i also absolutely looooove schlotskys deli vegetarian pizza (540 cal) it is sooo filling and good with the pesto and the sourdough crust and mmm all the veggies. and sbarros cheese pizza 1 slice (which is huge! 460cal)
all valid options for your common calorie counter. so i say, want pizza? have pizza! and dont you dare feel guilty over it.
