You could do a tasty stir fry with rice noodles. Just watch the soy sauce, though, as most varieties contains wheat. Or you could buy corn pasta (available from most supermarkets) and do something with that. Sainsbury's 'Free From' pitta bread are ok, as are their mini baguettes - we use either of these as a base for home-made pizza for my daughter. Corn tacos are also fine (you'll find with the Mexican range), filled with chilli, chicken or a filling of your choice.
