Cut the chicken breast into small pieces and marinate in 3 tablespoons of Kikkoman soy sauce for 1 hour.
Cut the nectarines into 6 pieces. Fry the nectarines in 1 tablespoon of olive oil for 30 seconds on each side until brown. In the same pan, add 1 tablespoon of olive oil and fry the chicken breast for 1 minute on each side.
Make a salad dressing: mix 1 tablespoon of olive oil, a teaspoon of soy sauce and 2 teaspoons of lemon juice.
Put the salad mix on a plate. Put the fried chicken breast next to it and the fried nectarines on top of it. Pour over the dressing.
