In a bowl, whisk together all marinade ingredients until smooth and glossy.
Add the chicken and toss until fully coated. Cover and marinate for at least 30 minutes (or up to 12 hours for best flavor).
Heat a large skillet over medium-high heat. Add a small drizzle of oil.
Add chicken in a single layer (shake off excess marinade for better caramelization).
Cook for 5–6 minutes per side until deeply browned, sticky, and fully cooked through (internal temp 165°F / 74°C).
Remove from heat and let rest for a few minutes before serving. Garnish with green onions and sesame seeds if desired.
