Cut a cucumber in half lengthways and scoop out the seeds, then cut in half lengthways again. Thickly slice into chunks. Toss together with 1 thinly sliced red onion, 350g (12oz) tomatoes and 50g (2oz) olives.
Whisk together 4 tablespoons oil, 1 tablespoon red wine vinegar, 1 teaspoon dried oregano, salt and pepper. Pour over the salad and toss until coated.
Finally add 150g (5oz) feta cheese, traditionally in one piece or crumbled into bite size pieces. Drizzle with a little more oil and sprinkle with a little extra oregano.
