To freeze: Allow the gluten-free fried rice to cool. Divide the rice mixture into 6 lunch-sized freezer containers or freezer bags. Remove as much air as possible, seal and freeze.
To serve in a lunch box: Thaw and heat mixture through. Place in a thermos bowl that has been pre-heated with hot water (put hot water in thermos bowl while heating rice. When ready to use, pour out water and add rice). Seal with thermos bowl cap.
To serve from frozen: If you have access to a microwave or stove at lunch time, place frozen rice container into lunchbox. Reheat at lunchtime according to microwave instructions or by heating in a small sauce pan on a stove.
