crockpot chicken cacciatore

from the crockpot cookbook (we have a 5-qt. model)

1 med onion, thinly sliced
3 lb chicken, cut up
12 oz tomato paste
4oz drained mushrooms (or about 3/4 C fresh)
1 tsp salt
1/2 tsp pepper
2 cloves minced garlic
2 tsp crushed oregano leaves
1/2 tsp basil
1 bay leaf
1/2 C dry white wine
1 lb cooked spaghetti

(NOTE: i added 1 can undrained diced tomatoes and about 1 C thinly sliced yellow zucchini because i like my cacciatore veg-ful)

place onion in bottom of crockpot, with drained mushrooms, drained (reserve juices) tomatoes and zucchini. place chicken atop veggies. combine tomato paste, wine, and spices, adding reserved juices from tomatoes if needed. pour atop meat & veggies. place bay leaves in sauce. cover & cook on low - 8 hours or high - 4 hours. serve atop spaghetti.
