Step 1

Thinly slice green onions and set aside. Cut chicken into 1-inch pieces. Combine chicken, salt, cornstarch, and water in a medium bowl; then, set mixture aside.

Step 2

Peel and finely grate ginger using a hand-held rasp-style grater or box grater; transfer ginger to a small mixing bowl. Grate or mince garlic. Add it to the ginger with the gochujang, mirin, honey, sesame oil, and vinegar, and stir until well-combined. Set sauce aside.

Step 3

Heat a large, heavy-bottomed frying pan over medium-high heat. Once hot, add oil, swirling to coat bottom. Add chicken and spread pieces into a single layer. Cook until well-browned on underside, 2-3 minutes. Turn pieces over and cook until browned on second side, 2-3 minutes. Transfer chicken to a bowl.

Step 4

Reduce heat to medium-low and add sauce mixture to pan. Cook, stirring constantly, until hot, about 30 seconds. Return chicken to pan and toss until well coated.

Step 5

Transfer chicken to a serving plate. Sprinkle with sesame seeds and reserved green onions, and serve immediately.
