This was great! I used everyone's suggestions here. Put the onions in with the chicken, but add the mushrooms and peppers in the last hour. I used green and red peppers and black olives - zucchini would have been good, too. I used chicken thighs, which fell off the bone, so I shredded the chicken before serving, which was easier that I thought it would be. We had it over mini penne pasta. I used a tablespoon of Italian seasoning, too. You won't be disappointed!
