I have an uncle with a gluten allergy. Not everyone has it to the same degree and he could eat small amounts of corn flakes. So he used those when breading instead of bread crumbs. They don't cover as well but when combined with cornmeal it's better. Still provides come crunch when oven "fried"

Another friend of mine (a caterer) just had her hubby diagnosed and is happily experimenting with different whole grain flours from the bulk store to create a bread that they can both enjoy. Buying from the bulk store keeps the costs way down.

Since your home anyway what about using your chef training to play around and see what you can come up with. A culinary success might lift your spirits. Who knows if you have a succession of them you could write a cook book or get some private clients, start a home based business. Try to focus on what you can do instead of what you can't

salads, beans, veggies...all good sources of fiber especially the beans. you don't need flour to live, you need the stuff flour supplies

There are a lot of gluten-free products out there now, more than there ever have been before. They are a little more expensive I think but you can get gluten-free bread (and often I think it is also whole grain) and even brownie mix. Look in the health food and organic sections in your grocery store. Health food stores have a lot of things too.

We have been experimenting with other starches like quinoa, which is a whole grain. Also rice, particularly brown rice and wild rice I bet if you googled "whole grains" you could come up with some good alternatives.
