Watermelon, Cucumber and Feta Salad

There are a lot of variations of this salad; I don't have an exact recipe.... just kind of wing-it!

cubed watermelon
cubed cucumber (take those wretched seeds out first)
diced red onion
cubed feta (I like to cut this myself so that the pieces stay in discreet squares)
chopped cilantro
salt and pepper
extra-virgin olive oil
lime juice to taste (not much, maybe one or two limes juiced)

In a separate small bowl, soak the onion in the lime juice while preparing the rest of the salad. In layers add the watermelon first, cucumber the red onion, chopped cilantro and feta on top. Season with salt and pepper, drizzle some EVOO over the whole thing (not a lot), pour the lime juice over and toss only when about to serve. It's a beauty of a salad.
