Stir the yogurt, ginger, soy sauce and lime juice together and pour half this mixture over the chicken.
Leave it in the fridge to marinate for half an hour.
Spray a frying pan with cooking spray and saute the marinated chicken over a medium high heat until it is cooked through.
Let it cool.
Chop the chicken and toss it with the avocado, mango, snow peas, eggs and onion, as well as the rest of the yogurt dressing.
Arrange the salad leaves on a serving platter and spoon the mango and chicken salad on top.
Decorate the platter with the tomato wedges and a sprig of parsley.
