Preheat air fryer to 400°. Toss chicken with cornstarch, salt and pepper. In batches, arrange chicken in a single layer on a greased tray in air-fryer basket. Cook until lightly browned and chicken is no longer pink, 4-5 minutes on each side.
Meanwhile, in a small saucepan, combine hoisin sauce, soy sauce, honey, ginger, garlic and pepper flakes; bring to a boil. Reduce heat; simmer, uncovered, until sauce thickens, about 5 minutes. Add cooked chicken; toss to coat.
Spoon chicken on bun bottoms; top with coleslaw mix and sprinkle with sesame seeds. Replace tops.
