Delicious! I used regular mushrooms as portobellos were spendy for a weeknight meal. I used 6 boneless/skinless chicken breasts, 1 1/2 pounds of button mushrooms and kept all the other ingredients the same. The sauce was excellent, although a bit watery for my liking the first day. The next day, however, is when it not only tasted even better, but the sauce was thicker. I made it with their Easy Baked Polenta which was a good pair. If you cut up the chicken smaller, you could serve this sauce over a thicker pasta: rigatoni, penne. Truly excellent chicken cacciatore!
