Slice and tenderize the beef with fat, then place in a mixing bowl. Add oyster sauce, soy sauce, fish sauce, and black pepper. Knead and mix well. Marinate for at least 3 hours (marinate in the morning and grill in the evening).

Grill over a charcoal grill with fairly high heat (but keep the grill rack not too close to the coals) until the beef is cooked to your liking.

Slice and serve on a plate with Jaew dipping sauce.
