I wanted a vegetarian version of chicken with white wine sauce that wasn't a total WW points-buster, and this recipe is what I arrived at. The portobellos and herbs help to flavor the seitan. If you'd prefer to go all-out, add more butter and cream to taste - the version here has just enough for me. Also, I highly recommend using a white wine that you'd actually drink - the flavor is noticeable in the final dish. I used a zippy New Zealand Sauvignon Blanc. Having never actually tried chicken with white wine sauce before giving up meat 10 years ago, I think this tastes great!!
