Step by step

Method

5 steps

1. 1

   Cut the sirloin into 1-inch cubes and toss with soy sauce, fish sauce, garlic, and a little pepper. Let it stand for 10 minutes while the pan heats.

2. 2

   Heat a wide skillet until very hot and add the oil. Sear the beef in one layer for 2 minutes, then shake or toss the pan and cook 1–2 minutes more.

3. 3

   Transfer the beef when the edges are browned and the centers are still juicy. Rest it while you make the salad base.

4. 4

   Arrange watercress with lime juice and sliced onion or tomato if available. Spoon the beef and its juices over the greens.

5. 5

   Serve right away with rice and extra lime. Taste the pan juices before adding more fish sauce.
