Rinse the chicken pieces under cold water and pat dry with paper towels.
In a large bowl, mix soy sauce, honey, gochujang, sesame oil, garlic, and ginger.
Add the chicken pieces to the marinade, ensuring they are evenly coated.
Cover and refrigerate for at least 30 minutes, or overnight for better flavor.
Preheat the oven to 200°C (400°F).
Heat vegetable oil in a large oven-safe skillet over medium-high heat.
Add the marinated chicken pieces skin-side down and sear for about 5 minutes until golden brown.
Flip the chicken and pour any remaining marinade over the top.
Sprinkle sesame seeds and green onions on top.
Transfer the skillet to the preheated oven and bake for 30 minutes, or until the chicken is fully cooked.
