I have made a baked seitan log that was supposed to be like sausage or pepperoni. It had the texture of meatballs or sausage when it was sliced and tasted slightly like sausage. My meat lovin' husband and kids enjoyed it. I think we may have fed it to some meat eater friends of my husband and they did not die
The recipe may have been a version of the seitan of greatness.
Give baked seitan a try, it is easy! I am sure there are recipes that have you flavor it in different ways and you could saute the outside to make it crispy.
