Follow these simple steps to create your Korean BBQ Chicken Bowls:

1. Marinate the Chicken: In a bowl, combine soy sauce, brown sugar, sesame oil, rice vinegar, minced garlic, grated ginger, and black pepper. Whisk well. Add the chicken thighs and coat them thoroughly. Cover and refrigerate for at least 30 minutes.

2. Cook the Rice: While the chicken is marinating, cook your rice according to package instructions. Set aside when done.

3. Prepare the Vegetables: Rinse and chop the broccoli, shred the carrots, and slice the bell peppers. You can steam the broccoli if you prefer a softer texture.

4. Cook the Chicken: Heat a grill pan or skillet over medium-high heat. Remove the chicken from the marinade and cook for 6-7 minutes on each side or until fully cooked. The internal temperature should reach 165°F (75°C).

5. Slice the Chicken: Once cooked, let the chicken rest for a few minutes before slicing it into bite-sized pieces.

6. Assemble the Bowls: In a bowl, start with a base of cooked rice. Top with sliced chicken, broccoli, shredded carrots, and bell peppers.

7. Garnish: Sprinkle chopped green onions and sesame seeds on top for added flavor and presentation. Serve with kimchi if desired.

8. Enjoy: Serve immediately and enjoy your delicious Korean BBQ Chicken Bowls!
