Make homemade teriyaki sauce by mixing the ingredients together in a small bowl.
Chop up the vegetables in 1-2 inch cubes.
Pour some of the homemade teriyaki sauce over the veggies, until all the vegetables are coated evenly.
Place the vegetables in the air fryer basket and cook at 380F/193C for 10 minutes. Optional: You can use a silicone basket to cook the vegetables. This would keep the teriyaki sauce from going to the bottom of the basket.
While the vegetables cook, cut the chicken into ½ inch thick slices. Stir in the teriyaki sauce, use enough to coat the chicken, but keep some (about ½ cup) to use as a glaze once everything is done cooking.
Lay the chicken on top of the vegetables. (With the chicken you can either lay them on top of each other or cook them in batches if they do not all fit inside the air fryer basket). Cook for 8 minutes at 380F/193C, flipping at the halfway point.
With remaining teriyaki sauce, there should be about ½ cup left. Add in about 1 tsp of cornstarch. Mix it together and microwave for about 1 minute 30 seconds to thicken the sauce.
Remove contents from the air fryer basket and place in a bowl. If you have any remaining chicken, cover the bowl with tinfoil to keep the food warm. Cook the remaining chicken in the air fryer basket at 380F/193C for 8 minutes, flipping halfway.
Add the chicken to the rest of the vegetable and chicken mixture. Enjoy with rice or quinoa, and teriyaki sauce.
