Wash your fresh ingredients thoroughly. Dice the watermelon into bite-sized cubes, slightly larger than the cucumber. Slice the cucumber into half-moons and crumble feta cheese into small pieces.

In a large mixing bowl, combine the diced watermelon, cucumbers, and crumbled feta. Gently toss until evenly distributed.

Finely chop fresh mint leaves and add them to the bowl. Toss gently to disperse the mint.

Squeeze fresh lime juice over the mixture and toss gently to coat the ingredients.

Transfer to a serving dish and chill for about 15 minutes before serving.
