To Prep
Whisk together fish sauce, sesame oil, soy sauce, lime juice, garlic, ginger and palm sugar in a jug.
Place the steak in a dish and drizzle half the dressing on ensuring the steak is coated all over. Cover with plastic wrap and place in fridge, turning occasionally for up to 2 hrs.
To Cook
Preheat a barbecue grill on high. Cook steak on grill for a few minutes on each side for medium, or cook to your liking. Transfer to a plate, cover with foil to rest for 10 mins.
Place the tomatoes, cucumber, chilli, onion, mint, coriander, basil, peanuts and lime leaves in a large bowl. Thinly slice steak and add to the salad. Drizzle with remaining dressing and gently toss to combine. Divide amongst bowls and serve immediately.
