Mmm... I haven't made Pizza Quiche in a while. Yours looks great. Looks about the same thickness as I'm used to.

I have the base saved as a custom food in Fitday (with a pretty low carb pizza sauce) and when you cut a whole pan into six pieces they're about 6g carbs a piece with a gram of fiber. I never had to freeze any of them. I usually eat all six pieces in a week, easy.
