Add chicken breast to slow cooker and add the salsa until the chicken is just covered (you may need more or less than 16 oz, depending on the size of your slow cooker and how much chicken you are using).
Cook on low for 5 hours.
After 4.5 hours, shred the chicken with 2 forks, then cook for the additional ½ hour.
Use in your favorite Mexican dish!
