usually fat free cheese tastes like... chemically plastic... I don't know how good this pizza could taste? and it is pricey... 6 pizzas are $37 with the shipping.
I sometimes make my own pizza with:
a whole wheat pita, I look for pitas around 100-120 calories, or sometimes use a high fiber, high protein, whole wheat 100 calorie english muffin.
tomato paste with some pizza seasoning and basil mixed in 25-40 calories depending how much you use
1/4 cup 2% shredded mozzarella 70-80calories
adds to about 250 calories, low fat from the cheese and extra fiber if you use a high fiber pita or english muffin.
