I'm wheat intolerant too. Like mommyB said rice cakes are a good alternative.
If your not on phase I, there's a good brand of bread called "Genius." I know Sainsbury's sells it and Tesco has a lot of wheat free rolls, cripsbreads etc. too. There are a lot of wheat free breads some not so good and some great. Just have to experiment and see what you like. Good luck.
