Sprinkle the rub mixture all over the pieces.

Shred the pork with two forks and stir in bbq sauce if desired.
Serve warm in sliders or with classic barbecue sides.
Notes
Instant Pot Instructions: Cook on high pressure for 60–70 minutes with a natural release. It won’t be exactly the same as 8–10 hours in a slow cooker, but it will still be tender.
Storage Instructions: Store in an airtight container for 3–4 daus. Freeze for longer storage.
