Sweet Onion Salad

Bring a large saucepan of lightly salted water to the boil. Add the onions and simmer for 20 minutes or until tender. Drain and set aside until cool enough to handle.

Thickly slice the onions and place in a shallow dish. Sprinkle the parsley and olives over and season to taste with pepper.

Whisk the vinegars and olive oil together in a bowl, then whisk in enough of the water to make a creamy vinaigrette.

Pour the dressing over the onions and olives and serve at room temperature.
