It's hard being new to this forum isn't it, so many things to learn, put in the right place etc. I've been reluctant so far as I'd hate to get it wrong, but I had to register today, want to add to your post.
I have been using Bowyers Low Fat sausages for 1 syn each if that's any help? They're quite nice. I think Quorn ones are free, but I don't like the texture.
Hope you found some info in the search x
