Start by preparing the lamb. Remove the fillet/eye of the meat from the bone and trim off all the fat. Discard the fat, but keep the bones and trimmings for stock to make lamb gravy. Cut the lamb into six small steaks. Place in a shallow dish. Mix the oil, garlic, herbs and seasoning together. Spoon half this mixture over the lamb. Heat the griddle pan or grill until very hot. Cook the lamb steaks according to your preference.
