Creating the savory Japanese BBQ Chicken Fried Rice Extravaganza can be simple if you follow these straightforward steps:

1. Prepare the Rice: Ensure the cooked rice is cold and break up any clumps to make it easier to fry later.

2. Marinate the Chicken: In a bowl, combine diced chicken thighs with 1 tablespoon of soy sauce and 1 tablespoon of BBQ sauce. Let it marinate for about 10 minutes.

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

4. Cook the Chicken: Add the marinated chicken to the skillet and cook for about 5-7 minutes until well-browned and fully cooked. Remove the chicken from the pan and set aside.

5. Stir-fry Veggies: In the same skillet, add the minced garlic and ginger, stirring quickly to avoid burning. Add mixed vegetables and sauté for about 3-4 minutes.

6. Combine: Return the cooked chicken to the skillet, mixing it with the vegetables.

7. Add Rice: Add the cold, cooked rice to the skillet. Stir well to combine all ingredients.

8. Season: Pour in the remaining soy sauce and BBQ sauce, mixing everything thoroughly. Drizzle sesame oil over the top for extra flavor.

9. Optional Eggs: If using, push the rice mixture to one side of the skillet and pour the beaten eggs into the empty space. Scramble until cooked, then combine with the rice.

10. Garnish: Once everything is heated through, sprinkle with sliced green onions and garnish with fresh cilantro if desired.

11. Serve Hot: Remove from heat and serve immediately while hot!
