01 - In a large salad bowl, combine the watermelon cubes, cucumber slices, red onion, and torn mint leaves. Toss gently to distribute evenly.
02 - In a small mixing bowl, whisk together the olive oil, fresh lime juice, honey, lime zest, sea salt, and black pepper. Whisk vigorously until fully emulsified and slightly thickened.
03 - Drizzle the dressing over the prepared ingredients. Using salad servers or large spoons, toss gently to coat all components without crushing the watermelon.
04 - Sprinkle the crumbled feta cheese over the top of the salad just before serving. Garnish with additional fresh mint leaves if desired. Serve immediately while ingredients are at their freshest.
