Chili con Cocoa for supper

Steve recently had a craving for homemade chili, and Julie suggested trying a chocolatey variant. The base recipe came from www.Hersheys.com but here it is after Steve's adaptations:

Ingredients:
1 onion, chopped
1 green pepper, chopped
1 lb mushrooms, chopped
1 lb ground beef
2 Tbsp cocoa
2 Tbsp chili powder or ground cayenne pepper
pinch of salt
1/2 tsp allspice
1 tsp cinnamon
1 can whole tomatoes, undrained
1 small can tomato paste
1 - 2 cups water
3 oz. dark chocolate (ours came from a chocolate bar, not baker's choc.)
1 can kidney beans, undrained
1 can other beans (ours included black and romano beans - chili needs a bean variety, IMHO)


Directions:
Cook beef in frying pan; drain fat if necessary. Add onions and fry 2-3 minutes. Add green pepper and mushrooms, fry another 2-3 minutes. Pour it all into a crock pot.
Add tomatoes, water, tomato paste, beans, and all spices to the crock pot, and stir to blend.Cook on High 30 minutes.
Break dark chocolate into small pieces. Add to crock pot and stir until melted. Cook on High another 3 to 4 hours.
Serve over rice.
