Add all ingredients to pressure cooker cooking pot.
Lock on lid and close pressure valve. Cook at high pressure (most machines default to high) for 3 minutes.
When Beep sounds, wait 10 minutes and then release the rest of the pressure.
Use an electric hand mixer and shred the chicken in the cooking pot. As the chicken shreds, the sauce will absorb into the chicken.
Alternatively, use two forks to shred the chicken.
