How to Make It

Beat the steak with a rolling pin until flat, then cut into two pieces.

In a bowl, combine the vinegar with salt, pepper and half of the oil. Place the steaks in the marinade and set aside.

Heat the rest of the olive oil in a pan on a medium heat. Cook the onions for 8-10 minutes, stirring until soft. Whilst the onions are cooking, bring a saucepan of water to the boil and cook the green beans for 5 minutes.

Push the onions to one side in the pan and place the steaks in the pan. Fry for 2-3 minutes, turning halfway.

Drain the beans and place them on the plates. Add the beef on top and serve with the rocket and beetroot wedges.
