Put dressing ingredients together.
Place steak into a food storage bag, pour in half the dressing, seal and make sure that the steak is well coated.
Refrigerate for at least ½ hour. If storing for longer, turn the bag occasionally.
Meanwhile, prepare the vegetables, herbs and nuts and assemble them in a salad bowl.
Pour in the remaining dressing and toss salad.
Remove marinated steak. Depending on the thickness and your preference, broil the steak for 3-5 minutes, turn and broil for another 3-5 minutes.
Remove and cover with foil.
Let stand for 10 minutes.
Slice steak thinly.
Place on top of salad and serve.
