Season the steak generously with salt and pepper. Sear in a very hot pan with the oil for about 2–3 minutes per side for medium rare. Rest for 10 minutes then slice thinly against the grain.
Whisk together the lime juice, fish sauce, palm sugar and chilli until the sugar dissolves.
In a large bowl toss the wombok, cucumber, mint and coriander with half the dressing.
Arrange the sliced beef and avocado over the salad, top with the peanuts then drizzle with the remaining dressing.
