Prep the air fryer by lightly spraying the air fryer basket.
Now, arrange the marinated chicken pieces in a single layer without over crowding. Lightly spray oil.
Put the chicken loaded basket inside the air fryer.
Press the ON button. You'll see the little screen light up with zeros.
Now press the AIR FRY button. Set the temperature to 350 F and the time to 6 minutes.
Finally, press the START button. The air frying process will begin. In case you want to check the chicken in between, just press the PAUSE button & take out the basket. Once done put it back in the machine. The air frying will begin once again from where you left it automatically.
After 6 mins take out the air fryer basket carefully. DO NOT touch the body of the basket it's VERY HOT. Flip the chickens and air fry for more 4 mins by following the same settings (350 F).
Once done, take out the chicken pieces and set them aside.
In the meantime set up your favorite skillet over high heat. Pour canola oil.
Throw the chopped garlic saute for a few seconds. Next, add the scallions (the white & light green part). Saute for a few seconds.
Next, add the onion squares. Saute for couple of seconds. The onions should remain crunchy so do not fry more. They will turn limp.
Add salt, all the bell peppers, the green leafy part of the scallion. Mix well.
Now, add the soy sauce, the teriyaki sauce, the green chili sauce & the ketchup. Mix well.
Add the corn starch slurry. Mix everything well until the whitish texture of the corn starch slurry completely disappears. It should take you a few seconds.
Finally, add the air fried chicken bites quickly. Mix over high heat, until the pieces are evenly coated with the sticky sauce.
Add the slit green chilies. Mix. turn off the flame.
Garnish with chopped scallions & serve immediately. Enjoy!
