In that case, I'd suggest you look at the Paleo Diet or Paleo eating plans. Check out Mark Sisson's blog at: www.marksdailyapple.com/
and look for the reader cookbook under Freebies. I also like the recipes at: paleodietlifestyle.com/paleo-diet-recipes/
and while both sites do have books to sell, the free recipes and info is ample for anyone to explore eating Paleo-style as a GF option.
I myself have been following a Paleo eating plan for the last 2 years. I've seen health improvements on a number of levels. Paleo is grain-free and dairy-free and I find it much easier to follow than the standard Celiac diet.
Frankly, after discovering I was gluten intolerant and dairy intolerant, I found that trying to duplicate the 'old' lifestyle by substituting GFCF processed foods was completely unsatisfactory as well as expensive. By shifting to Paleo I adopted a 'real foods' diet and sidestep all the issues surrounding cross-contamination. There's a whole world of great food out there that doesn't come in a can or a box.
So get un-depressed
there are lots of tasty options out there!
