J.S.
I know many blogs that can help you find a recipie you would consider. I will paste those at the bottom of this message. if you do not want to go to the trouble of cooking, then Whole Foods offers many gluten free desserts in their frozen food section. Not all are casein or soy free, but the section is 100% gluten free made in a dedicated kitchen. Any tips, ideas, etc. you need feel free to private message me. I also have to be gluten free (and soy free -- a very good friend of mine has to be gluten, soy, and casein (dairy) free so we trade recipes all the time)
