M&S sell gluten free sausages - but disguised as nomal sausages - look for the symbol on the pack to make sure you get the right ones.
They are in packs of 20 in a meat type tray rather than a packet. £4.49 per packet, but they are included in the 3 fo £10 promotion.
I am sure they will be tasty, and at this price the whole family can eat gluten free.
