Seitan Stroganoff

I was craving this tonight - I made it vegan but it can easily be made dairy. The recipe (from mom way back when) Only with vegan ingredients subbed in:

1 tsp smart balance
1 package seitan
1 white onion
1/2 package sliced white mushrooms
1 Tbsp vegan worchestershire
1 cup veggie broth
2 Tbsp flour
1/2 tsp mustard
1/3 cup red wine
1/3 cup sour cream (I used the better than sour cream stuff- I like it)
Na++ and pepper
Noodles

Saute seitan in smart balance. Add onions and mushrooms and saute until soft. Add worchestershire and saute until all brown. Add flour to broth, then pour into side of pan and stir until thickened. Incorporate into the rest of pan. Add mustard (take it easy, it can overpower) and wine. Let reduce just a bit. Add sour cream, salt and pepper and that's it. Serve over noodles. Yum.
