01 - Place the cubed watermelon, sliced strawberries, blueberries, and chopped mint in a large salad bowl. Toss gently to distribute the mint evenly throughout the fruit.
02 - In a small bowl or jar, whisk together the lime juice, honey, lime zest, olive oil, and sea salt. Whisk vigorously for 30-60 seconds until the mixture emulsifies and thickens slightly.
03 - Pour the honey lime vinaigrette over the fruit mixture. Using a large spoon or salad tosser, gently fold the fruit to coat evenly without crushing the delicate berries.
04 - Sprinkle crumbled feta cheese over the top just before serving, if desired. Serve immediately in chilled bowls, or refrigerate for up to 1 hour for a colder presentation.
