To prepare the steak:
Season the steak pieces well with a drizzle of oil, salt and pepper.
Heat the pan/grill to high (you may add more oil depending on the kind of pan you are using).
When smoking hot, place the steaks (you need to hear that sizzle). Cook on high heat for 2 minutes; turn to medium heat and continue cooking for another one minute. Turn and cook for a further 1-2 minutes for a medium steak or continue cooking till done.
Remove and allow to rest for 5 minutes before serving.
