Put your diced chicken, sesame or olive oil, salt, minced garlic, pepper, rice vinegar, hoisin sauce, soy sauce and chicken broth into your pressure cooker. Stir.
Close pressure cooker lid and steam valve and set to high pressure for 4 minutes.
Do a quick release when done. Open lid and set aside.
In a small bowl whisk together your cornstarch and 5 tbsp of hot liquid from your pot until smooth.
Set your pressure cooker to saute and when sauce inside begins to bubble pour your cornstarch mixture in and stir for 1 minute. Then turn pot off.
Dice green onions and put into pot, add as many roasted cashews as you'd like. Stir so everything is combined well.
