I think that it is OK as long as the sugar is 2gms or less per serving. I tried to look it up in the book but couldn't find it. Maybe somebody else will know the exact amount of sugar.
GET THE BLOODY RECIPE ELLIS!!! I WANT IT!! By the way, Marie's dressing has 0 carbs!!! But it is easy to use a LOT of those thick dressings, so you have to be careful!!!
Marie's Light Blue Cheese is good. It has hardly any sugar & is really delicious. Regular Marie's is good too, but has too much fat, I'm afraid I'll use too much. I tried the zero calorie, no carb dressings, but they were not very tasty. I figure why cheat your tummy!
Another good one is Light Done Right (kraft)... I have the bottle at work and I can't remember how many grams of sugar but I think 3 ... I've been making my own dressing so often lately ...
