HI Teresa, from my experience, a lot of diatitions/nutritionists don't know much about celiac disease and for me anyways, they haven't been much help. I think I've educated them more on what options are out there, they any ideas or advice they've given me.
Anyhow, as far as grains you can eat corn, rice, quinoa, and some oats (depending how they were processed and stored) Irish oats are supposedly safe.
You can buy pasta made from rice, corn or quinoa flours, I recommend the Tinkyada brand, I've found it to be the best in texture and taste.
There's a great company called Gluteno that makes awesome Bagels and their corn bread is pretty decent...it takes some getting used to but out of all the gluten free breads I've ever tried, this one has been the best.
Gluteno has a pretty good line of products from breads to cookies and crackers. Safeway has started carrying some of their products, Fred Meyer is another that has a large Gluten Free selection of products and Whole Foods is another great place to get gluten free goods.
You can also order Gluten free foods online there are several websites check out glutenfree.com
For goodies check out a brand called The Cravings Place, they have the best brownie mix I've ever had, gluten free or otherwise.
Aside from all that, get used to reading labels, gluten is in EVERYTHING! well it seems that way sometimes
Soy sauce, most salad dressings, some cream cheeses, some yogurts. You have to read the label on everything, until you know which products are safe.
At first it seems like there are no options but once you look around there are so many. New ones are popping up all the time now too with the heighten awareness on Celiac disease. Even a lot of restaurants now offer gluten free options.
