Creating a wonderful Teriyaki Chicken Stir-Fry is straightforward. Follow these simple steps:

1. Prepare the Teriyaki Sauce: In a small bowl, whisk together soy sauce, honey, rice vinegar, minced ginger, and garlic. Set aside.

2. Marinate the Chicken: If you have time, marinate the sliced chicken in part of the teriyaki sauce for about 15-30 minutes to enhance flavor.

3. Heat the Oil: In a large skillet or wok, heat the vegetable oil over medium-high heat until shimmering.

4. Cook the Chicken: Add the marinated chicken to the skillet. Sauté for about 5 minutes or until fully cooked and golden brown. Remove from the skillet and set aside.

5. Sauté the Vegetables: In the same skillet, add the mixed vegetables. Stir-fry for about 3-5 minutes until tender but still crisp.

6. Combine Chicken and Vegetables: Return the cooked chicken to the skillet with the vegetables.

7. Add the Teriyaki Sauce: Pour the prepared teriyaki sauce over the chicken and vegetables. Stir to coat everything evenly.

8. Thicken Sauce (Optional): If you want a thicker sauce, mix cornstarch with water in a small bowl. Add this slurry to the stir-fry and cook for an additional minute, stirring frequently.

9. Garnish: Sprinkle with chopped green onions and sesame seeds before serving.

10. Serve Hot: Serve the stir-fry immediately over rice or noodles for a complete meal.
