01 - In a large mixing bowl, whisk together the gochujang, soy sauce, rice vinegar, honey, minced garlic, grated ginger, sesame oil, and black pepper until smooth and well combined.
02 - Add the chicken pieces to the marinade, tossing to coat evenly. Allow to marinate for at least 20 minutes at room temperature, or cover and refrigerate for up to 2 hours for deeper flavor penetration.
03 - Heat a large skillet or non-stick pan over medium-high heat. Add the marinated chicken along with any excess marinade. Cook for 6–8 minutes per side until the chicken is fully cooked through and develops a caramelized, slightly charred exterior.
04 - Remove the skillet from heat. Sprinkle with toasted sesame seeds and sliced green onions. Serve hot alongside steamed rice or wrapped in crisp lettuce leaves.
