Heat your frying pan on a very high heat. Trim any fat from the steak and slice into super fine strips. Drizzle with a little olive oil and season.

Cook beef in the hot pan for about 1 minute. Then stir and keep cooking till browned on all sides.

Meanwhile, combine lemon juice and 4 tablespoons extra virgin olive oil in a bowl.

When the steak is cooked transfer to the lemon dressing.

Toss in rocket leaves. Serve with parmesan shaved over.
