I have to have a gluten free kitchen, so I bake our bread. My husband absolutely will not eat anything with tapioca flour in it. He cannot abide the taste. I bought a new bread machine that has a special cycle to bake gluten free bread and now it is easy to do. There are a few good boxed bread mixes on the market, you just need to try them and see which ones you prefer. Another idea is to make tortillas instead of sandwiches. Just put your hamd and cheese, or bacon and tomato on the corn tortilla and fold and eat. About the only thing we haven't found a substitute for that we are happy with is a non-wheat pasta. We have completely given pasta up and now do not miss it.
If you can tolerate oats, then 5 Minute Brand Oatmeal is gluten free, absolutely no cross contamination in their factory. My husband eats it with no problem. That is the only brand he can tolerate. I called their company and checked about their processing; it's safe.
