In a bowl, whisk together gochujang, soy sauce, mirin, honey, grated garlic, sesame oil, and ginger to make the sauce.
Cut chicken thighs into bite-sized pieces and toss in the sauce to coat well.
Heat canola oil in a large skillet over medium-high heat.
Add the marinated chicken and cook, stirring frequently, until chicken is cooked through and sauce thickens (about 12-15 minutes).
Sprinkle toasted sesame seeds and sliced green onions on top just before serving.
Serve hot over cooked rice for a complete meal.
