Mix the spices in a bowl then rub the steaks with it.
Mix the oil and lemon juice and drizzle over the steaks. Massage them well, then out them in a glass dish and chill for at least a couple of hours, preferably overnight.
Heat your BBQ, grill or griddle pan.
Season the steaks with salt and pepper then fry/grill them for 3-5 minutes on each side, turning them a couple of times.
When the steaks are cooked to your liking, transfer them to a plate and rest for a couple of minutes before serving with your chosen side dishes.
