This salad, with its cool cucumbers and watery watermelon, is so thirst quenching it is like drinking a very flavourful glass of water!
Per serving:
Using vegetable peeler or mandoline, slice cucumbers very thinly lengthwise to create ribbons. Place in large bowl; add mint, feta, watermelon, and salt.
In small bowl, whisk together oil and lemon juice and pour over salad. Let stand at room temperature for 30 minutes. Add pistachios, garnish with mint leaves, and serve.
