I was happily surprised with this dish, and so was my husband! A couple notes... I used much more red pepper flakes - almost a full teaspoon (we like our food spicy). Also, I omitted mushrooms because I had none on hand but I think I like it better this way anyway. Also, since I omitted mushrooms, I doubled the onions. Lastly, we are not on diets so we used regular chick broth and regular sour cream. The result was a very filling, creamy and substantial dinner. We will definitely make this a regular on our meal repertoire. The chicken came out really tender!
