Place steak, soy sauce, garlic and lime juice in a bowl and allow to stand for 10 minutes. Cook steak on a preheated hot char grill for 1-2 minutes on each side or until cooked to your liking. Cover steak and set aside. Arrange lettuce, mint, basil, coriander and cucumber on serving plates. Slice beef thinly and place on top of salad.

Combine all ingredients and give a good shake to dissolve sugar and mix the flavours. Pour dressing over the salad and serve.
