Begin by selecting a ripe, seedless watermelon and a fresh English cucumber. Cut the watermelon into bite-sized cubes, approximately 1-inch pieces, and slice the cucumber into half-moon shapes. Aim for about ¼-inch thickness for the cucumber to maintain crunch. Set the prepared ingredients aside, and take a moment to appreciate their vibrant colors.

In a large mixing bowl, gently combine the cubed watermelon, half-moon cucumber slices, and crumbled feta cheese. Use a spatula to fold the ingredients together carefully, so the watermelon stays intact and the feta lightly coats the other components.

Once combined, allow the salad to chill in the refrigerator for about 15 minutes. This brief refrigeration will help the flavors meld together beautifully.

After chilling, give the salad a gentle toss to mix any settled ingredients. Serve immediately for the freshest taste.
