Creating Chicken Sushi Bowls is straightforward if you follow these clear steps:

1. Rinse the Rice: In a fine-mesh strainer, rinse the sushi rice under cold water until the water runs clear.
2. Cook the Rice: In a pot, combine the rinsed rice and water. Bring to a boil over high heat. Once boiling, reduce to a simmer, cover with a lid, and cook for about 15 minutes or until the water is absorbed and the rice is tender. Remove from heat and let it steam for an additional 10 minutes.
3. Prepare the Chicken: While the rice is cooking, cut the chicken breast into bite-sized pieces.
4. Marinate the Chicken: In a bowl, mix the soy sauce, rice vinegar, and sesame oil. Add the chicken pieces to the marinade and let them soak for about 10-15 minutes.
5. Cook the Chicken: Heat a skillet over medium heat. Add the marinated chicken and cook for about 6-8 minutes or until fully cooked, stirring occasionally.
6. Slice the Vegetables: While the chicken is cooking, prepare the cucumber, carrot, and avocado.
7. Assemble the Bowls: Once the rice is cooked and chicken is ready, fluff the rice with a fork. Divide the rice evenly among serving bowls.
8. Layer Ingredients: Top each bowl of rice with the cooked chicken, sliced cucumber, shredded carrot, avocado slices, and strips of nori.
9. Garnish: Sprinkle sesame seeds over the top and add chopped green onions for extra flavor. If desired, serve with pickled ginger and wasabi on the side.
