The first time I had chicken cacciatore in a restaurant, it was made with skin-on, bone-in chicken. The skin was so yucky and the bones were hard to deal with through the sauce. This recipe uses bite size, skinless, boneless pieces so there is nothing to fight with or yuck up the sauce. All the veggies in the sauce give it a wonderful texture and flavor. This recipe would probably work in a crock pot, but I haven't tried it that way yet.
