Place chicken in slow cooker. Top with remaining ingredients. Cover and cook over low for 6-7 hours. This can be served several ways. You can shred the chicken in the slow cooker, stir and serve. Or, you can remove the chicken breasts and top with the salsa mixture in the slow cooker. You can also have the leftover shredded mixture on a whole wheat tortilla or over lettuce for a Tex/Mex salad.
