Add everything to a slow-cooker except shrimp, parsley and salt and pepper. Stir together and cook on low for 7-8 hours or high for 4 hours. During the last 10 minutes, stir in the shrimp and remove bay leaves. When shrimp are pink and cooked through, it is ready to serve. Season with salt and pepper to taste. To serve, use a slotted spoon, then go back and add as much of the liquid to each dish as is your preference using an unslotted spoon. Serve with steamed white rice and fresh parsley.
