1. Combine the marinade ingredients and spread over the meat. Allow to marinate for at least two hours.
2. Preheat a large frying pan and add the oil. Add the meat to the pan in batches, cooking for one minute per side, then remove to a platter to rest. If you’re not serving it immediately, refrigerate it until you’re ready to use.
3. Meanwhile, combine the ingredients for the parsley salad. After steaks have rested, cut them into about six pieces each to fit the cucumber slices (not into strips). Arrange the steak pieces on top of the cucumber slices, then top with parsley salad.
