Mix it all up. Serve or refrigerate for a day. Note: If your meal has no other oils or fat in it, splash a bit of light-flavored olive oil on this salad for better vitamin absorption.
I've made many versions of this, including with other melons or sturdy fruit, as well as chunks of jicama. Use what's sweet & ripe. Smaller amount great with cottage cheese instead of feta for lunch or cool summer dinner.
