01 - Place the watermelon cubes, quartered strawberries, and blueberries in a large mixing bowl. Gently mix to distribute the fruits evenly.
02 - In a small bowl, whisk together the fresh lime juice, lime zest, honey or agave syrup, and sea salt until the honey is fully dissolved and the mixture is well combined.
03 - Drizzle the citrus dressing over the fruit mixture. Using a large spoon or clean hands, gently toss the fruit to ensure every piece is evenly coated with the dressing.
04 - Sprinkle the finely chopped fresh mint leaves over the dressed fruit. Give the mixture one final gentle toss to incorporate the mint throughout.
05 - Cover the bowl and refrigerate for at least 10 minutes to allow flavors to meld. Serve chilled for maximum refreshment. Best enjoyed within 24 hours.
