Watermelon and Feta Salad

Steps

1. 1
   Chill the watermelon thoroughly before cutting — the temperature contrast with the feta is most of the pleasure.
2. 2
   Cut it into 3 cm cubes, removing the seeds, and drain off any loose juice.
3. 3
   Slice the onion paper-thin and soak it in cold water for 10 minutes, then dry it.
4. 4
   Arrange the watermelon and feta on a wide platter rather than tossing them in a bowl, which breaks the feta down.
5. 5
   Scatter over the onion, torn mint and olives if using.
6. 6
   Dress with the lime juice and olive oil and grind over plenty of black pepper. Do not add salt — the feta has it covered.
7. 7
   Serve immediately, while it is still cold.
