Remove the steaks from the fridge 1 hour before cooking.
For the bean salad, in a large bowl combine all the ingredients together with 1 tablespoons of oil, season, toss gently, cover and set aside for 10 minutes to infuse the flavours.
For the dressed rocket, in a large bowl, gently toss the rocket and lemon juice together, cover and set aside.
Heat a large non-stick frying pan over high heat until hot.
Brush the steaks on both sides with the remaining oil and season.
Reduce the heat under the frying pan to moderate and cook steaks for 1-2 minutes on each side, adding the garlic and herbs (if used).
Remove the steaks from the pan and slice across the grain.
Spoon a portion of the rocket leaves on a serving plate. Lay the steak slices over the rocket. Garnish with the Parmesan and serve the bean salad on the side.
