I came up with this when I couldn't decide between chicken cacciatore or something more Tex-Mex. I also wanted a "real" meal without having to work too hard at it. We really enjoyed this. Other cuts of chicken can be used, although I recommend staying away from boneless skinless breasts because I think they tend to dry out in a slow cooker. Since every one's crock pots heat differently and grains can be tricky to cook in a CP, you may have to fool a little bit with the timing on the rice and barley. You could also make that separately and just add it in at serving time. Cooked the way I did it, it almost had a risotto-like texture to it.
