In a large bowl or on a serving platter, gently combine the watermelon, feta, cucumber, onions, mint, and basil.

Drizzle with olive oil and lime juice. Lightly season with salt and black pepper (go easy on the salt—feta is already salty).

Use your hands or a large spoon to mix everything gently, so the feta doesn’t break up too much.

Serve immediately or chill for up to 30 minutes before serving.
