Layer the chicken thighs in the slow cooker, followed by the salsa verde, cumin, lime juice, garlic, and jalapeño (optional), no need to stir. Cover and cook for 4 hours on high.
After 4 hours, turn the slow cooker to warm. Using tongs remove the chicken thighs and place in a heat safe bowl. Allow to cool enough to touch and slide the skins and bones off the chicken. Use two forks to shred the chicken. Return the chicken to the sauce and reheat. Taste, add salt if necessary.
Use the chicken and sauce in your favorite foods. Chicken enchiladas, tacos, dips soup, over rice, etc. See original blog posts for my favorite applications.
