Fill a large mixing bowl with the cubed watermelon and sliced cucumber. Ensure the watermelon pieces are uniform for even mixing and visual appeal.
Drizzle the olive oil and honey over the fruit and vegetables, then gently toss with a large spoon or spatula until evenly coated. Look for the shiny, lightly dressed appearance.
Add the crumbled feta and chopped mint leaves to the bowl. Carefully fold them into the mixture, resulting in a colorful, textured salad.
Season the salad with salt and black pepper to taste, adjusting until flavors are balanced. The salt should subtly accentuate the feta and watermelon.
Transfer the salad to a serving platter or individual bowls. Garnish with additional mint leaves if desired, then serve immediately for freshness.
