Although inspired by Marc Bittman's idea for a watermelon salad, to me, this would hardly be worth mentioning if it were not for the Persian cucumbers the watermelon is combined with. These cucumbers take the Kirby to another level: smaller cukes, even smaller seeds and much sweeter, too. Shred some fresh mint leaves, and you're done. Dressing? Not for me, but if you prefer one, I'd suggest the simplest of vinaigrettes with a mild vinegar, perhaps a rice wine vinegar. But, as I say, in my opinion, it needs absolutely nothing else but a fruits a vegetable, and an herb.
