As someone who is not too fond of peanut butter, I am amazed at how much I love this dish! It tastes even better as leftovers. I normally tire of leftovers after a day or 2. I had 4 days worth and was disappointed when I realized I was down to my last serving.
I recommend crunchy peanut butter as others have suggested. And, I also suggest not using the entire cup of cooking liquid. Maybe 1/2 to 3/4. I eliminated the chicken and it was just fine.
