Creating your Teriyaki Chicken Casserole is easier than you might think. Follow these simple steps for a delicious meal:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C).
2. Cook the Chicken: In a large skillet, heat olive oil over medium-high heat. Add diced chicken and season with garlic powder, ginger powder, salt, and pepper. Cook until the chicken is browned and cooked through, approximately 6-8 minutes.
3. Prepare Vegetables: Once the chicken is cooked, add the broccoli, bell peppers, carrots, and frozen peas to the skillet. Stir and cook for another 3-4 minutes until the vegetables are slightly tender.
4. Mix Rice and Sauce: In a large bowl, combine cooked rice with the teriyaki sauce. Mix well to ensure the rice is evenly coated.
5. Combine Ingredients: Add the chicken and vegetable mixture to the bowl with the rice. Stir well to incorporate everything.
6. Transfer to a Casserole Dish: Pour the mixture into a greased 9×13 inch casserole dish, spreading it evenly.
7. Add Cheese: Sprinkle the shredded cheese over the top of the casserole.
8. Bake: Place the casserole in the preheated oven and bake for 25-30 minutes or until the cheese is melted and bubbly.
9. Garnish: Remove from the oven and let it cool for a few minutes. If desired, garnish with chopped green onions before serving.

These straightforward instructions will enhance your cooking experience, allowing you to create a comforting meal that your family will love.
