Combine all ingredients in slow cooker. Cover and cook on low for 6 hours or until chicken is tender and cooked through. Shred using two forks, and mix with sauce.
If desired, cook for another hour on low before serving or freezing.

Notes
I use medium salsa but use whatever type of salsa you like best.
Meat will be a little juicy. If you want, drain some of the juice off before using.
