Rinse 200 grams of rice under cold water until the water runs clear. Place the rice in a pot with 400 ml of water and a pinch of salt. Bring to a boil, cover, and reduce heat to low. Cook for about 15 minutes or until the rice is tender and water is absorbed.
Cut the chicken breasts into bite-sized pieces.
In a large bowl, combine soy sauce, honey, rice vinegar, cornstarch, garlic powder, ginger powder, salt, and pepper. Mix well to create a marinade.
Add the chicken pieces to the marinade and stir until well-coated. Let marinate for about 10 minutes.
Heat sesame oil in a large skillet or wok over medium-high heat. Add the marinated chicken to the skillet, spreading it out evenly. Cook for about 5-7 minutes, stirring occasionally, until the chicken is browned and cooked through.
Add the sliced bell pepper and julienned carrot to the skillet, and stir-fry for another 3-4 minutes until the vegetables are tender-crisp.
Serve the cooked rice in bowls, topped with the sesame chicken and vegetables. Garnish with chopped green onions and a sprinkle of sesame seeds.
