Well, in Eating for IBS there's a great tuna salad recipe... (sorry, don't have the book in front of me. ) and it calls for pasta. If I don't have any gluten-free pasta around, I will use rice noodles for things like that. Tip: don't use the teeny tiny noodles for something of this nature, 'cause they're just not substantial enough to "hold" the heavy tuna. Use the fatter rice noodles.
Mostly I make the rice noodles as described (or a variation thereof) and use it as a side for just about everything. If I've got some chicken or salmon and don't feel like making rice, then off to the side go some rice noodles. I've found that by tinkering with that basic recipe, you can make that sauce go with tons of stuff. Example: substitute lemon for lime if you used lemon on your fish.... add different herbs that complement what's on your chicken, etc...
Once I was craving marinara sauce (which doesn't bother my tummy) but was too dang lazy to make gf-pasta (you know, that 10 minutes boiling time was too taxing for me! ), I tossed it on some fat rice noodles. Tasted great.
I'm sure there are tons of other things to do with them. Lemme see what I can come up with. It will be good for me to expand my menu choices!
