Remove steaks from the fridge preferably an hour before you want to cook them, or as long as you’ve got.
For the dressing, combine vinegar with 2 tablespoons extra virgin olive oil.
Heat a frying pan on a medium high heat. Add a little olive oil and the broccoli / broccolini and a splash of water. Cover and cook stirring every few minutes until the veg are no longer crunchy, about 5-10 minutes. Place veg in a clean bowl.
Increase heat to medium high. Rub steaks with a little oil and sprinkle with salt.
Cook steaks for 3-5 minutes each side, or until cooked to your liking.
Place steak on 2 plates. Drizzle over dressing and allow to rest for 5-10 minutes before serving with the broccolini / broccoli on top and extra sea salt flakes.
