Using a strainer, rinse the rice until it’s no longer cloudy then allow to drain for 10-15 minutes.
Add the rice and 2 cups of water to the Instant Pot.
Stir, close and lock the lid and turn the valve to sealing position. Set to manual / pressure cook, high pressure for 3 minutes.
When done, allow for a 10 minute Natural Pressure Release (NPR) followed by a Quick Pressure Release.
Open the lid, fluff the rice using two forks and transfer it to a bowl.
Set the Instant Pot to Sauté mode and add in sesame oil.
Once the oil begins to sizzle, add the chicken. Season with garlic powder, onion powder, salt, and pepper. Cook for 5-7 minutes, until the chicken is nicely browned.
Add the onion and sauté for another 1-2 minutes. Then add the peas, carrots, corn, and butter and cook for an additional 2 minutes.
Push the chicken and veggies to one side of the insert and add the eggs to the other side, quickly scramble, then combine with the other ingredients.
Turn off the Instant Pot, add the rice back along with the soy sauce, rice vinegar, and sesame seeds, stirring to combine.
Serve topped with additional sesame seeds and chopped green onions.
