We are egg and peanut. We use the hidden valley packets (mainly for dip) and Kraft free ranch. Not exactly rich and creamy, but if you're trying to lose weight...
My egg allergy isn't severe, but if you are looking for something that's a little bit more creamy, Kraft's Light three cheese ranch reads as egg free, and I use it. Not full fat, but it does have a bit more substance than the Kraft Free.
YMMV - My egg allergy has never been severe, and I'm not PA or TNA.
