WOW! I tried this recipe the other night, and my whole family agreed it is a keeper! Adding this to my favorite recipes file- we will make this again and again! I would suggest that you DON'T substitute things in this recipe because it is THAT good when you follow it exactly. The only thing I did slightly differently was I added about 1/2 of my chives while the sauce simmered (before adding sour cream) and the rest were stirred in at the end. It was simply divine! Always looking for new ways to prepare chicken because my fiance gets bored of the same recipes, and this is a happy addition to our file!
