01 - In a small bowl, whisk together the soy sauce, mirin, rice vinegar, honey, sesame oil, garlic, and ginger until well combined.
02 - Heat a large nonstick skillet over medium-high heat. Add the chicken pieces and cook for 4–5 minutes until lightly browned and nearly cooked through.
03 - Pour the teriyaki sauce mixture over the chicken. Cook for 2–3 minutes, stirring constantly, until the sauce begins to bubble.
04 - Stir in the cornstarch slurry. Continue cooking for another 2–3 minutes, stirring frequently, until the sauce thickens and evenly coats the chicken.
05 - Serve immediately over steamed white rice, sprinkled with sesame seeds and sliced spring onions.
