Mix cubed pork with all ingredients except stock. Allow to marinate for 20 minutes.
Add everything to the pressure cooker and cook at pressure for 30 minutes, then allow 15 minute natural release.
Remove the meat and spread out on a foil-lined baking dish (lasagna pan, something with sides so juice won't run off). Drizzle with a few tbsp of the cooking liquid and broil 5 minutes, then flip the meat cubes, drizzle again and broil another 5 minutes.
