Watermelon cold
enough that it hurts your teeth;
feta; red onions,
lime juice, salt, crushed red peppers
and candied tangerine peel!*
*(canola or olive oil if you must; sub. basalmic {real! so use just a few drops, possibly mixed in with the lime juice?} if you like. I have yet to try oil-cured black olives – pitted if you like your guests – but with the feta cubes, why not?)
