Season the sliced pork with the salt and the pepper, making sure to coat all sides.
Place in the slow cooker, fat side up. This allows for the fat to drip down and confit, making a juicy final product.
Add the remaining ingredients into the slow cooker. Place the lid and slow cook on High for 7 Hours.
After 7 Hours, remove the lid and turn off the slow cooker. Shred the pork with a fork. Place all the contents in a large mixing bowl.
Press Sauté for 30 Minutes. Add a tablespoon of vegetable oil and a quarter of the shredded pork. Sauté undisturbed until browned, about 8 minutes. Remove from the pan and toss with leftover sauce to stay juicy. Continue working in batches until all pork is lightly golden.
Serve with warmed tortillas, jalapenos, cilantro, and diced white onion. Enjoy!
