Marinate the Chicken: Combine soy sauce, miso paste, and 1 teaspoon of sesame oil. Marinate the chicken breast for 15-20 minutes to enhance flavor.
Cook the Chicken: Pan-sear or grill the chicken on medium heat for 5-6 minutes per side, or until fully cooked. Let it rest briefly, then slice thinly.
Prepare Vegetables: Thinly slice the cabbage, julienne the carrot, and slice the cucumber. Keep the veggies cold to maintain crispness.
Make the Dressing: Mix rice vinegar, 1 teaspoon of sesame oil, and a dash of soy sauce. Optionally, add a pinch of sugar or honey for sweetness.
Assemble the Salad: In a large bowl, layer the greens, cabbage, carrot, and cucumber. Arrange the sliced chicken on top and drizzle with dressing.
Garnish: Sprinkle sesame seeds over the salad. Add optional toppings like avocado or edamame for extra texture.
Serve: Serve immediately and enjoy the fresh flavors of this Japanese chicken salad.
