gluten-free eats

White rice
Plain rice cakes
Boiled potatoes (no skin no butter)
White-meat chicken (no skin)
Plain white fish (flounder etc.)
Silken tofu
Lowfat dairy or equivalent, including plain yogurt (I know a lot of people say to avoid this, but it works for me)
Applesauce (small quantities)
Well-cooked carrots or squash (strain out pulp, or use baby food)
Small amounts of eggs (boiled/poached - you don't want to add fat) or dishes made with them (like custard)

Another thing to avoid except in small quantities is fruit juice. The sudden simple sugar hit can be very stimulating. Diluted pulp-free OJ or apple juice might be OK is small quantities.
