Slice the watermelon into bite-sized cubes, ensuring they're about an inch each for easy chewing.

Wash and peel the cucumber, then cut it into similar-sized pieces to match the watermelon.

Crumble the feta cheese into small chunks and set aside.

In a large mixing bowl, gently combine the watermelon, cucumber, and crumbled feta cheese.

Use a spatula to lift and fold the ingredients together carefully for about 2-3 minutes.

Squeeze fresh lime juice over the salad, using about one to two limes.

Gently toss everything together for another 1-2 minutes.

Transfer the salad to a covered bowl and place it in the refrigerator to chill for approximately 30 minutes.

Once chilled, stir the salad gently and transfer it to your serving dish. Garnish with fresh mint leaves or basil if desired.
