To your Instant Pot, add in your ginger, sweet onion, garlic, chicken bouillon, sugar, fish sauce and water. Stir everything together.
Next, add in your chicken thighs and close the seal. Ensure that the pressurized cap is sealed.
Set your Instant Pot to Meat for 45 minutes and let cook.
Once the timer beeps, release the pressure by turning pressurized seal to release or open and let all the steam out for a few minutes.
When safe and no more steam is coming out, open the lid and add in your pepper and green onions. Add in salt to taste but is optional if it is salty enough for your taste buds.
Serve on a warm bed of white rice and enjoy!
