Drizzle 2 tablespoons fish or soy sauce over the steak and allow to marinate while you heat a pan on a high heat.

Pan fry the steaks for about 3 minutes on each side until cooked to your liking.

Meanwhile, combine lime juice with remaining 3 tablespoons fish sauce and the chilli.

When the beef is cooked, transfer to the dressing and rest for a few minutes.

Finely slice the steaks and return to the dressing. Toss in the salad leaves and serve immediately.
