With all my recipes (and since I always make adjustments), I just add up the carbs as I add the ingredients. Then I divide by however much of the total I eat at that meal.

And Pizza Quiche is great! -- it never affects my ketosis even with all the cheese. Since I don't like anything on TV on Wednesdays and I don't get home until 8:30 p.m., every Wednesday is Pizza Quiche and Movie Night!
