🍉 Bright, juicy watermelon meets creamy feta, zingy pickled onions, and garden-fresh mint in this unforgettable summer salad.

Every summer, like clockwork, I find myself slicing into a watermelon that’s just perfect—crisp, juicy, and sweet enough to make you pause mid-bite. But as much as I love eating watermelon straight from the cutting board, I wanted something a little more special for backyard dinners and potluck tables.

This salad was born out of that craving—an easy, elevated take that’s both refreshing and wildly flavorful. The combo of salty feta, quick-pickled red onions, and cooling mint brings out the absolute best in that summer melon. It’s light but satisfying, sweet yet savory, and pretty enough to steal the show at any garden gathering.
