I first heard of watermelon salad from a friend who spent some time in Australia. Watermelon salads were very popular there at the time and just about unknown here. Later, I found this very simple, but very yummy recipe and tried ir for myself. I hope you'll try it for yourself, too, if you already haven't. This salad is very refreshing ; the sweetness of the watermelon is offset by the tanginess of the arugula and the goat cheese.
