This is really delicious, one of my favorite crock pot recipes that can as easily be made as a casserole and baked in the oven. It lends itself easily to your favorite variations. I did not include boiling the chicken in the time since that is an option, and you can use already prepared cooked chicken, and I listed the time for oven baking, not the crock pot version. You can either cook a whole chicken in water with your favorite seasonings to make the broth, or use cooked chicken use canned broth. Works well either way. I've had it a long time and can't remember the source.
