Mix all the dry ingredients in a bowl, add the lime juice. Plop the pork in a Dutch oven and coat the meat with your spice mixture. Add a cup of water.
Cover the pan and roast at 300 degs. Turn the pork about every 45 minutes or so. Do this for about 2 hours plus. Add another ½ cup of water with the butternut squash, cook for 30 minutes. Add the tomatoes and kale and cook for 15 minutes more. There you are serve it up!
