1In a large bowl, combine the watermelon cubes and cucumber slices.
Drizzle the lime juice over the watermelon and cucumber mixture.
Gently toss the ingredients to ensure they are evenly coated with the lime juice.
Finely chop the fresh mint leaves and sprinkle them over the salad.
Give the salad one final gentle toss to distribute the mint leaves.
Serve immediately or refrigerate for up to 1 hour before serving to allow the flavors to meld.
