I love the Quest chips also, but have not tried the sour cream and onion yet--only sea salt, cheddar, and salt and vinegar so far. I can take them to work and it takes me a while to eat them as part of my lunch. Yum!
My favorite Quest bar by a long shot is double chocolate for my restricted. I save my restricted for the evening and I take a long time to eat them. I will read up here for other options. I will have to look for Kay's Naturals.
When I was on IP the first time I lived on the dark chocolate pudding. I don't think that anyone has ever found a decent sub for that, but throwing that out in case anything has changed. Thanks.
