Preheat air fryer to 390F (200C).
In a food processor add the corn flakes, salt, pepper, garlic powder and paprika. Pulse until cereal is broken down into rough crumbs. Pour into a large bowl.
Place flour in a separate plate, and in a third bowl whisk together egg, milk or buttermilk and tablespoon of buffalo or chili sauce.
Coat each chicken strip in flour, shaking off extra flour. Dip the chicken in the egg mixture evenly on both sides, then roll in corn flake mix generously. Place on baking sheet and repeat with all the chicken.
Place in air fryer basket and fry for 5 minutes, then toss around and fry for another 5 minutes until cooked through.
Once cooked, place the 1/2 cup chili sauce in a shallow bowl, add each chicken strip to the bowl and toss to coat. Enjoy immediately!
