Creating the Blackstone Hibachi Chicken Dinner is straightforward if you follow these easy steps:

1. Preheat the Griddle: Turn your Blackstone griddle to medium-high heat and let it preheat for a few minutes.
2. Prepare the Marinade: In a bowl, mix 1/4 cup of soy sauce, minced garlic, and grated ginger. Combine thoroughly.
3. Marinate the Chicken: Add the chicken pieces to the marinade, ensuring they are well-coated. Let them sit for 5-10 minutes.
4. Cook the Chicken: Add vegetable oil to the heated griddle. Once hot, place the marinated chicken on the griddle and cook for about 5-7 minutes or until golden brown and cooked through.
5. Add the Vegetables: Push the chicken to one side of the griddle. On the other side, add the mixed vegetables. Season with salt and pepper and cook for 3-5 minutes until tender.
6. Combine Ingredients: Stir the chicken and vegetables together on the griddle. Pour the remaining marinade over the mixture, allowing it to cook for another 2-3 minutes.
7. Drizzle with Sesame Oil: Once everything is cooked through, drizzle sesame oil over the chicken and vegetables for an added depth of flavor.
8. Garnish and Serve: Sprinkle with sliced green onions and sesame seeds before serving.
