Start by combining in a small saucepan, the ketchup, apple cider vinegar, brown sugar, drained pineapple chunks, diced green bell pepper, diced red bell pepper, and onion.
Simmer the sauce, for about 5 minutes, until everything is well combined. Let cool, slightly.
Diced your chicken into 1-inch pieces.
To prepare the packages, place the chicken in a piece of foil, and then scoop some of the sweet and sour sauce on top.
Fold up the edges, so you have a packet that will not leak.
As you make the packages, place them in the air fryer.
Set the time for 15 minutes at 350 degrees F.
After the time is up, flip and set the time for another 7 minutes.
After the time is up, check and see if the chicken is cooked. Mine was fully cooked, if yours is not, add a few minutes more.
Plate, serve and enjoy!
