Thank you, both. I've tried the tortillas, but not with very good results. Seems like they either get soggy or so crispy, they aren't very edible.
I love the Boboli crust, but thought it seemed a little high in calories for me.
I've read about using pitas, so maybe I can find some whole wheat/grain pitas & check out the calorie content on those.
Or maybe I just have to face facts that pizza IS a high calorie food
Sometimes, a girl just gots to have it, though
