In a bowl, mix soy sauce, sesame oil, honey, rice vinegar, garlic, ginger, black pepper, and red pepper flakes.
Add the sliced chicken to the marinade and let it sit for at least 15 minutes.
Heat vegetable oil in a large pan over medium-high heat.
Add marinated chicken and cook for 5-7 minutes until browned and cooked through.
Push the chicken to one side and add shredded cabbage and carrots to the pan.
Stir-fry the vegetables for 3-4 minutes until slightly softened.
Mix everything together, then remove from heat and garnish with green onions and sesame seeds.
Serve hot with rice or lettuce wraps.
