Finely dice the ginger and garlic, then combine with the sesame oil and soy sauce.

In a bowl or plastic bag combine the steak and marinade and leave for at least 1 hour.
Preheat the grill grates to medium-hot.
Place the steak on the preheated grill and cook to get grill marks of your liking. Check the internal temperature of the steak, if not cooked to your desired temperature, move to a cooler part of the grill and let slowly come up to temperature.
