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 crisp 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.
Once the chicken is fully cooked, remove and set the foodi to the saute function. Note - this can also be made in a small saucepan. Add in the pineapple, onion, bell pepper, pineapple juice, soy sauce, Worcestershire sauce, brown sugar, and ginger.
Bring this up to a low boil for about 2-3 minutes or until the veggies are soft.
Lower the heat and whisk in the cornstarch, if using the Ninja Foodi pot, use a silicone ended whisk.
