I love quinoa. Its a godsend for gluten free vegetarians as its a complete protien and gluten free all in one.
I like to make quinoa, and top it with olives, garlic, tomato/spaghetti/pizza sauce (just be careful, some sauce mixes aren't gluten free), and mozzerella(sp?) cheese. Gluten free pizza bowls! I like jalapenos in them sometimes too.
I have quinoa pasta and honestly I like it more than ANY wheat pasta I ever ate.
But a word of caution, the kind I have is made of a mix of quinoa and corn flour, and I know a lot of celiacs are also allergic to corn.
Ive been at this a long time and Im STILL getting glutened. There was so much I didn't realize had gluten in it.

Most commerical ranch dressing mixes at restaurants have it. I found that out today and was bummed because salad is one of the only options I had left for eating out and I dont like salad without ranch. Even the italian dressings at my work have gluten.
Good news: The SUNBIRD brand stir fry sauces I LOVE are gluten free, I was avoiding looking into it because I was scared of what I might find out (dumb I know lol) but luckily the news was good. Most of the sauces are vegan and gluten free, but you have to use a gluten free soy sauce to make them. Being vegetarian I love stir fry.
I also found out today LAYS STAXX chips are gluten free, the entire line. Not only are they themselves gluten free but they are free of cross contamination issues, unlike the rest of the LAYS brand, which are made on the same lines as the gluten stuff.
