Use a fork to poke holes into the chicken and place the chicken in a large bowl or in a Ziploc bag.
Make the sauce.
Remove 1/4 cup of juice from the canned pineapple and drink the rest as your reward. Set aside the pineapple chunks.
In a small microwave safe bowl, mix together 1/4 cup of pineapple juice, soy sauce, sugar, ketchup, ginger and garlic.
Pour half the sauce over the chicken Mix until the thighs are well-coated with the marinade. Reserve the rest of the sauce to cook as a dipping sauce (below).
Set aside the chicken to marinate for 30 minutes or up to 24 hours in the refrigerator.
Place the marinated chicken in the airfryer at 360F for 15 minutes, turning half way through.
Meanwhile, place the reserved sauce in the microwave and cook on high for 45-60 seconds, stirring every 15 seconds. You are going to cook this until you get a thick glaze or pouring sauce that you can use with the cooked chicken
Using a meat thermometer, ensure your chicken has reached an internal temperature of 165F.
Remove chicken to a serving tray, garnish with pineapples and green onions and serve with the thickened sauce poured over all of it.
