Use a 6-quart slow cooker. Put the chicken into the bottom of your stoneware. Add chopped apple, onion, and bell pepper. Add garlic and all spices. Toss in the raisins and the entire can of diced tomatoes. Stir in the chicken broth. Cover and cook on low for 6 hours, or until chicken is tender, but still intact. Using tongs, remove chicken carefully from the slow cooker and place in a covered dish to keep warm.
