Pre-heat your grill or BBQ to medium-high.

Rub the steak all over lightly with oil and season generously with salt and pepper. Cook over a medium-high heat for 2 minutes, then turn and cook for a further 2 minutes.

Turn again, this time at a 180-degree angle and cook for another 2 minutes. Turn for a final time and cook for 2 more minutes.

The steaks should be cooked medium-rare and be neatly cross-hatched with marks from the grill.

Use the thumb-to-finger rest for doneness, or check the interior of the meat with a meat thermometer.

Transfer steaks to a warm plate and cover them loosely wit foil. Leave to rest for 4 minutes before serving.

Serve with mustard or relish, or top with your favourite flavoured butter.
