Cut the chicken, potato, carrot, and onion into bite-sized pieces.
Place the prepared ingredients, soy sauce, sugar, cooking wine, minced garlic, pepper, and water in a microwave-safe dish.
Cover lightly with plastic wrap or a lid, and microwave for 9-12 minutes.
Take it out halfway, stir the ingredients, and microwave again for 4-6 more minutes.
Add green onion and sesame oil to the finished chicken, and mix well before serving.
