Sprinkle the pork shoulder with Herbs de Provence (or Italian seasoning) and sea salt and gently press into the meat.
Place the pork shoulder in the slow cooker, along with the diced onion, garlic, and apples.
Pour the apple juice and chicken broth into the slow cooker. Cover, and set slow cooker on low for 6 to 10 hours, until meat is very tender and pulls easily away from the bone.
Transfer the pork to a cutting board and use two forks to shred the meat. Transfer the shredded meat back into the crock pot, discarding the bone.
Allow meat to sit in the juices at least 1 hour before serving (if possible).
Taste the meat for flavor and add sea salt to taste.
Cook the rice according to package instructions. While rice is cooking, saute the chopped kale in a small amount of olive oil in a skillet over medium-high heat until wilted, about 5 minutes.
Add desired amount of rice to bowls and top with sauteed kale, pulled pork and apples, and sliced avocado.
Spoon the pork-apple juice from the crock pot over the bowls and sprinkle with sea salt.
Serve with lime wedges and enjoy!
