Once the oil gets hot, sear the pork for 2 to 4 minutes until brown.
Arrange the seared pork in a slow cooker and add all the ingredients except for the salt and pepper in a slow cooker. Cover and slow cook in high mode for 4 hours (if you have time, set it to low and slow cook for 8 hours).
Remove the cover. Gently stir the mixture and add salt and ground black pepper as necessary.
