Begin by thoroughly washing the watermelon to remove any surface contaminants. Cut it into bite-sized cubes and place them into a spacious mixing bowl.
Next, layer the crumbled feta cheese on top of the watermelon, ensuring to distribute it evenly for balanced flavor in every bite.
Take the red onion and slice it very thinly, then gently add the onion slices to the bowl, spreading them throughout the salad.
Finely chop the fresh mint leaves, and sprinkle them generously over the watermelon and feta for a burst of fresh flavor.
In a separate small bowl, whisk together the balsamic glaze and olive oil until they are completely combined into a smooth dressing.
Carefully drizzle the balsamic and olive oil mixture over the salad ingredients, taking care to coat them evenly.
Using a large spoon or spatula, gently toss the salad to combine all the ingredients, ensuring not to break the feta cheese.
Season the salad with kosher salt and freshly ground black pepper to enhance the flavors, mixing delicately to maintain the integrity of the feta.
For optimal flavor, allow the salad to rest for about 10-15 minutes before serving to let the ingredients meld together beautifully.
Notes
Serve in a large, shallow bowl and garnish with additional mint leaves and a drizzle of balsamic glaze before serving.
