Turn the Instant Pot to sauté mode and add olive oil. Sprinkle chicken breasts with salt and pepper to taste, then sauté in the Instant Pot for a few minutes per side.
Whisk together all other ingredients in a small bowl until a sauce has formed.
Turn off the Instant Pot and add sauce, then mix until combined.
Set the Instant Pot to manual, set the timer for 10 minutes on High Pressure, and seal the lid.
Once the time is up, let the pressure naturally release. Remove chicken and shred it, then taste it and add more salt and pepper as needed.
Prepare a bowl with cauliflower or white rice, Chinese Five Spice Chicken, carrots, cucumbers, lime, and herbs. Spoon more sauce over the top and enjoy!
