Start by making your Labneh. For this you'll need a bowl, a sieve and a clean muslin cloth. Drape the muslin cloth over the sieve and place into a bowl. Pour the yoghurt into the cloth, and season with the salt. Leave it to thicken overnight (the longer you leave it, the thicker it will become) and then scrape the delicious, creamy labneh out of the muslin cloth and onto your dish.
Ensure your Bavette Steak is thoroughly thawed. Before cooking, allow the steak to dry out and reach room temperature.
Generously season the steak with good quality salt and pepper and drizzle it with a little olive oil.
Cook the steak over your BBQ or in a cast iron pan for about 5 minutes, until a caramelised crust has formed. Turn the heat down slightly and cook for another 4 minutes on each side. Leave to rest in a warm place for at least 5 minutes before carving.
Wash your radishes and warm your flatbreads.
Slice your steak and place on top of the labneh. Enjoy!
