Step 1 Measure dressing ingredients into a screw-top jar. Shake to combine.

Step 2 Place steak in a plastic bag then add half the marinade mixture. Massage bag to cover steak with marinade then set aside for 20-30 or more minutes (or refrigerate overnight). Add lemon or lime juice to the remaining marinade in jar. Shake to combine then set aside.

Step 3 In a large bowl toss all the salad vegetables except avocado.

Step 4 Preheat barbecue to a high heat and lightly oil the hotplate. Remove steak from marinade and place on the hotplate. Cook for 2-3 minutes each side or to your preference. Remove steak from hotplate and allow to rest for about 5 minutes before cutting into 5mm slices.

Step 5 While steak rests, peel and slice avocado then toss with other vegetables and half the remaining dressing. Arrange salad greens on individual plates or on a platter. Fan steak slices over greens and drizzle with the remaining dressing. Serve immediately.
