Shredded Chipotle Pork Tacos

1. Heat oil over medium-high heat in a very large skillet. Once the oil is hot, add the pork in a single layer. Cook, stirring occasionally, until the meat has browned, about 6 to 8 minutes. Cook the meat in batches, if necessary, to avoid overcrowding the pan. When the meat is browned pour the meat and the juices into a slow cooker.
2. Pour the next 9 ingredients (onion through salt) into the slow cooker with the pork and stir to combine. Cook for 6 hours on the highest setting.
3. After 6 hours, carefully stir the mixture, breaking up the pork as you stir. The pork should fall apart. Taste and season with a little more salt, if needed.
4. Scoop pork into a large bowl and serve with warm corn tortillas, diced red onions, cilantro, cheese and avocado.
