Cut the chicken breasts into bite-sized cubes and set aside.
Prepare three bowls: one with flour, one with whisked eggs, and one with panko breadcrumbs.
Season both the flour and breadcrumbs with salt, garlic powder, and black pepper.
Coat each chicken piece in flour, then dip into the egg, and finally coat with breadcrumbs.
Arrange the coated chicken in a single layer in the air fryer basket and lightly spray with oil.
Cook at 200°C (400°F) for 15 minutes, flipping halfway, until golden and crispy.
Meanwhile, prepare the sauce: heat sesame oil in a saucepan over medium heat.
Add garlic, then stir in honey, soy sauce, sweet chili sauce, and water mixed with cornstarch.
Simmer until slightly thickened. Season with salt and lemon juice.
Toss the cooked Air Fryer Honey Garlic Chicken Bites in the sauce until fully coated.
Serve immediately with sesame seeds and chopped green onions if desired.
