Watermelon and Feta Salad

This is my way of pretending winter isn't happening.

Watermelon and Feta Salad
from Nigella Lawson's Forever Summer
Serves 8

1 small red onion
2-4 limes, depending on juiciness
1.5 kg sweet, ripe watermelon
250g feta cheese
Bunch fresh flat-leaf parsley
Bunch fresh mint, chopped
3-4 tablespoons extra virgin olive oil
100g pitted black olives
Black pepper

Peel and halve the red onion and cut into very fine half-moons and put in a small bowl to steep with the lime juice, to bring out the transparent pinkness in the onions and diminish their rasp. Two limes should do it.

Remove the rind and pips from the watermelon, and cut into approximately 4cm triangular chunks. Cut the feta into similar sized pieces and put them both into a large, wide shallow bowl. Tear off sprigs of parsley so that it is used like a salad leaf, rather than a garnish, and add to the bowl along with the chopped mint.

Tip the now glowingly puce onions, along with their pink juices over the salad in the bowl, add the oil and olives, then using your hands toss the salad very gently so that the feta and melon don't lose their shape. Add a good grinding of black pepper and taste to see whether the dressing needs more lime.
