Take steak out of fridge and get to room temperature for 30-40 minutes. Oil the steaks on both sides.
Take a pan to smoking hot temperature then sear steak for 1 minute and then turn temperature down to medium and cook for 2 minutes.
Flip it and salt the steak turn temperature up and sear for 1 minute. Turn temperature to medium and cook for 2 minutes.
Now put a heaped tablespoon of butter, with herbs and garlic if you desire then baste the steak. Leave to rest on warm plate or in foil parcel for 5-6 minutes.
If your steak is thinner reduce cooking time.
For the chimichurri chop the pepper, parsley, oregano and shallot, finely, mince the garlic. Now add oil and vinegar until it's a sauce that can fall off a spoon. Add the cayenne and honey to taste.
Serve with some new potatoes or whatever you fancy.
