It's not as good as Shyvas's shamefully sexy pic above, but I had a bash at some seitan facon. The texture is good, but the smokey flavour I aimed for didn't come through. I also should have upped the salt a bit, maybe not as much as the whopping 2-3% in pig bacon. I'd call this a partial success and I'll make it again with improvements.
The pink layers are flavoured with tomato/paprika/black pepper and the white layers nooch/mustard.
I barely kneaded it, then wrapped it in aluminium foil, then cling film, and boiled it for an hour. Then it's good to slice thinly and fry. Freezes nicely too.

Looks good. The pic isn't mine but from the Seitan Appreciation Society.
