01 - Pat the chicken pieces dry with paper towels. Toss with salt, pepper, and cornstarch until evenly coated.
02 - In a small bowl, whisk together honey, soy sauce, rice vinegar, ketchup, garlic, ginger, and chili flakes if using. Set aside.
03 - Heat vegetable oil in a large skillet or wok over medium-high heat. Add chicken in a single layer; cook 5–7 minutes until golden and cooked through, turning occasionally.
04 - Pour the sauce over the chicken. Stir to coat and bring to a simmer. Cook 5–7 minutes, stirring often, until the sauce thickens and becomes sticky.
05 - Remove from heat. Garnish with sliced green onions and sesame seeds. Serve hot over steamed rice or with your choice of sides.
