Cut the chicken into chunks and coat with cornstarch, use about 1/4 cup and then add more if needed to fully coat the chicken.
Spray the air fryer basket with olive oil cooking spray.
Add the chicken and cook at 390*F for 10 minutes, open the lid, stir it up, and spray another coat of oil.
Cook for an additional 5-10 minutes or until the internal temperature reaches 165*F.
In a small saucepan, combine the pineapple, onion, bell pepper, pineapple juice, soy sauce, Worcestershire sauce, brown sugar, and ground ginger.
Bring this up to a low boil for about 2-3 minutes or until vegetables are soft.
Lower the heat and whisk in the cornstarch.
Let it sit for about 2-3 minutes to thicken.
Mix with the cooked chicken and serve with rice.
