Gently toss the salad in a large mixing bowl until combined. Be careful to not mash up all of the watermelon cubes! I like to let my watermelon feta salad sit in the refrigerator, covered, for a bit (even up to an hour or so!) to let the flavors really meld.
Drizzle each portion with a generous swirl of Homemade Balsamic Glaze. Top with extra salt and pepper if needed and enjoy!
