Italian Chicken

1 lb. chicken breasts
8 oz. sliced mushrooms (I leave this out because I think that mushrooms look like brains)
1 green bell pepper, chopped
1 zucchini, diced
1 onion, chopped
26 oz. spaghetti sauce (I use the Classico Tomato & Basil because it is sugar free)
Spaghetti or other pasta

Combine all ingredients (other than the pasta) in the crock pot and cook on low for six or eight hours. Serve over cooked pasta.
