Crockpot Chicken Ragu Over Polenta

This sauce is usually served over pasta, but I thought it might be nice over polenta. It is spicy and full of flavor and the polenta balances that out with it's creamy, salty flavor.

2 chicken breasts
1 carrot, diced
2 celery stalks, diced
1 onion, diced
1 tsp salt
4 cloves of garlic, minced
1/2 small can of tomato paste
3/4 c red wine
1 32 oz can whole tomatoes
1 tsp thyme
1 tsp oregano
1 tsp basil
1 tsp red peper flakes (use less if you don't like spicy)
1 recipe Perfect Polenta

In a saute pan over medium high heat, brown chicken on all sides. Remove chicken and add carrot, celery, and onion. Cook until just softened. Add to crockpot and add garlic, tomato paste, wine, tomatoes, and herbs. Turn crockpot to high for 3 1/2 hours or low for 6. After cooking for 3 hours (if cooking on low, 5 if cooking on high) remove chicken and shred, return to crockpot and break up tomatoes. Allow to finish out cooking time. Serve over polenta.

Be warned, this didn't photograph well!!
