Remove bone and cube pork into 1x1" pieces, put them into your pot.
Add all other ingredients and stir together so meat is coated.
Close pressure cooker lid and seal steam valve and set to high pressure for 25 minutes.
Allow for a natural release of steam for 5 minutes, then release the rest quickly.
Lift lid and use forks or tongs to shred meat (will fall apart). If you want some of the liquid to evaporate you can set pot to saute for about 5 minutes and then serve inside tortillas or on top of rice.
