Cucumber, red onion, and pink peppercorn salad

Serves 3-4 as a side dish Preparation time: 20 minutes (includes marinating time) Cooking time: nil

I had a flatmate once who used to make a salad from thinly sliced cucumber and onions, bathed in malt vinegar.

It was surprisingly good, in a very retro way, but I prefer this prettier and more refined version.

1 medium size red onion, peeled and finely sliced teaspoon salt teaspoon caster sugar 4 tablespoons rice wine vinegar 1 tablespoon extra virgin olive
