My seitan substitute of choice: Chai Pow Yu. Comes in cans at Uwajimaya and other Asian stores. Nummy. High in fat, though. I rinse it before using it.

Try putting other fresh herbs in the biscuit dough, too.

You're reminding me that I should maybe post the Chai Pow Yu Gulyas (goulash) recipe that invented itself in my kitchen a couple weeks ago. Awwwwwesome. The recipe it was inspired by used seitan, but the only seitan I could find had stuff I was allergic to in it. This is when Chai Pow Yu (which is really basically the same thing, plops of wheat gluten) came to the rescue!
