Add the chicken, salsa verde, salt, and cumin to a slow cooker. Mix it all together, then add the lid, and cook it for 2 ½ to 3 hours on high, or 4 to 5 hours on low.
Using tongs, remove the chicken to a cutting board and shred with two forks.
Return the shredded chicken to the slow cooker and stir together. Garnish with fresh cilantro before serving.
