Begin by mixing together the corn starch and spices. Chop the chicken into bite size pieces. Toss in the corn starch mixture and let rest it for 30 minutes or more.

Chop all the vegetables into bite size pieces and begin sauteing over medium heat. Season with salt and pepper to taste.

Once vegetables are half way cooked, put the chicken in the air fryer at 400° F for 8 minutes.

Add the soy sauce, tomato paste, vinegar, and sugar to the vegetables to make the sauce, and bring to a simmer.

Once the chicken is done and the vegetables are fully cooked, add the chicken and pineapple to the sauce and stir to combine. Return to a boil to allow the chicken to soak in the flavor of the sauce. Once the chicken is fully coated and the sauce is your desired thickness, remove the pan from the heat.

Serve over rice, or along with your favorite Chinese dishes.
