OK, I had a look in Sainsbury's and Waitrose. There are, in fact, a LOT of cereal bars that are both dairy- and soya-free. They're mostly ones I avoid because I hate raisins, which is why I didn't know how many there were.

Would you like me to buy you a load and put them in the post? I know you're really short of energy to be able to face going to the supermarket and reading all the labels, and it's relatively little hassle for me. (It's something I feel comfortable committing to).

Is there anything else you avoid apart from dairy and soya? (e.g. nuts?)
