Place the pork in the slow-cooker. Using a sharp pairing knife, insert the knife into the pork about 1 inch deep and insert the crushed garlic, rubbing any excess garlic all over the pork.
In a small bowl, mix together all ingredients for the spice rub.
Rub the dry spice rub evenly all over the pork.
Pour the chicken broth into the slow cooker and add the bay leaves and green chilies.
Cover and cook on low for 8-10 hours or on high for 4-5 hours.
When tender, remove the meat and place on a plate. Using two forks, shred the meat, discarding any fat. Add the pulled pork back to the slow cooker, discard the bay leaves and mix into the remaining juices. Serve on buns, wraps, brown rice or quinoa.
