3. Cover and cook on low for 6-7 hours or high for 3-4 hours, until the chicken is tender and easy to shred.
4. Remove the chicken, shred it with two forks, and set aside.
5. In a small bowl, mix cornstarch with water and stir into the sauce in the slow cooker. Cook on high for 10-15 minutes until the sauce thickens.
