Cut the base from the oranges so they sit flat, then pare away the skin and pith. Cut each orange into round slices.

Peel and finely slice the onion into rounds. If you want a milder flavour, soak the slices in boiling water for a few seconds and then drain immediately. Don’t leave to long in the hot water or they will loose their crunch.

In a bowl, mix the orange, olives and onion together, sprinkle with salt, pour over the oil, sprinkle over the parsley, toss again and serve.
