Hi Lizzy, All,
I had exactly the same question today. I went an bought those oat cakes in Holland & Barrat (UK Health food chain shop).
I actually went in looking for ‘oat bran’ – I heard this was ok for porridge as opposed to regular oats (which I had been eating).
The main diet on the website also said quinoa crackers might be ok or oat bran crackers, but I couldn’t find any of those.
Maybe I can try to make some based on the above recipe, I just really struggle to find time to cook with my work 🙁
