01 - Combine the watermelon cubes, quartered strawberries, and blueberries in a large mixing bowl. Handle the fruit gently to avoid crushing the delicate berries.
02 - In a small bowl, whisk together the fresh lime juice, lime zest, honey or agave syrup, and a pinch of sea salt. Continue whisking until the honey completely dissolves and the mixture is well emulsified.
03 - Drizzle the citrus dressing evenly over the prepared fruit. Using a large spoon or silicone spatula, gently fold and toss the mixture until all pieces are lightly coated with the dressing. Take care not to mash the watermelon.
04 - Sprinkle the chopped fresh mint leaves over the dressed fruit. Give the salad one final gentle toss to distribute the mint evenly throughout the mixture.
05 - Cover the bowl and refrigerate for at least 10 minutes, or up to 2 hours for enhanced flavor. Serve chilled for maximum refreshment. The salad is best enjoyed the same day it is prepared.
