  1. I added chicken breast pieces to mine, and followed the recipe perfectly. It was absolutely delicious. I served with wild rice, but next time I think I’ll double the sauce and cook pasta and toss it all together with the extra sauce.  Delicious, thanks for this great recipe I see myself using in so many different ways!
