Place the chicken breasts in your slow cooker and add water or broth until the chicken is covered. If you'd like to add any optional seasonings or herbs, feel free. Cover and cook on low for 7-8 hours or on high for 3.5-4 hours.

Remove the breasts to a cutting board and discard the cooking liquid. Shred the chicken using two forks (it should fall apart easily). You can use other methods to shred if you prefer (stand mixer on low, etc).
