Combine salt, sumac, paprika, onion powder, garlic powder, black pepper, and oregano. Mix well in a bowl and rub meat with seasoning. Place meat in fridge for one to two hours. Take out of fridge five minutes before cooking.
Heat sunflower oil in a large cast iron or Dutch oven over medium-high heat. When the oil is hot and a little smokey, add the meat and sear until golden brown on all sides. If using a braising pan, transfer meat and leftover liquid/grease from cast iron to braising pan.
Add vegetable stock/water, apple cider vinegar, tomatoes, chopped garlic, medium diced onion, Navajo tea bundle, and sage to the Dutch oven or braising pan. Cover, or double foil. Braise at 200 degrees for 3-1/2 to four hours, or until tender (easy to pull).
Place meat in a separate pan and shred. Blend liquid and braised vegetables with a hand blender or a tabletop blender. Place meat back in pan with liquid, cover and keep warm.
