I am gluten intolerant (not medically diagnosed, definitely not celiac, but through an elimination diet I've established that gluten definitely causes me huge GI issues). I figured this out in the late 90s and I can categorically state that more than 95% of all GF breads you buy are simply horrible and NONE of them are edible without being toasted. The only brand that I've found that's palatable is Whole Foods Market in house variety (the prairie bread, in particular).
If you don't have a Whole Foods market available try going into a very, very good health food store that has a comprehensive selection of GF foods and ask for their recommendations. Finally, IMO the GF varieties of Van's waffles are really good and make a tolerable bread substitute -- well, at least for something like peanut butter and jelly or toasted with butter.
