In a large bowl mix all the ingredients together using your hands. Place in the refrigerator for at least 30 minutes to get all the flavours to develop.
Meanwhile, take the salad leaves and place in a large bowl. Now mix the oil, lemon juice and mustard and dress the salad in the bowl coating each leaf with the dressing. Top with a sprinkle of rock salt.
Divide the mix into 4 and make into a round shape and place on a plate. Then use a fork to make a pattern with the meat.
Serve with the salad
