In a large mixing bowl, combine the diced watermelon and cucumber. The sweetness of the watermelon pairs perfectly with the crispness of the cucumber, creating a refreshing base for the salad.

Add the crumbled feta cheese and chopped mint leaves to the bowl. The feta adds a salty creaminess, while the mint provides a fresh aroma and flavor.

In a small bowl, whisk together the olive oil, lime juice, honey (if using), salt, and black pepper. Whisking emulsifies the dressing, ensuring all ingredients are well combined and evenly distributed.

Taste the dressing and adjust seasoning if necessary. You may want to add more lime juice for acidity or honey for sweetness, depending on your preference.

Pour the dressing over the salad mixture and gently toss to combine. Be careful not to crush the watermelon or feta while mixing.

Transfer the salad to a serving bowl and garnish with additional mint leaves if desired. Serve immediately for the best flavor and texture.
