1Combine watermelon, cucumber, sweet onion, fresh basil, feta cheese, and pecans,optionally, in a large bowl. Sprinkle lightly with salt, and allow ingredients to macerate in juices, refrigerated, for around one half hour. (Watermelon will release quite a bit of juice.)
2Just before serving, drizzle balsamic vinegar and honey on top. Toss and serve immediately.
