Prep your ingredients: Cube the watermelon and feta into even bite-sized pieces; about 1-inch chunks work best for skewers.
Assemble the skewers: Thread watermelon, a folded mint leaf, and feta onto each skewer. Repeat once or twice depending on the size of your skewer and appetite.
Add a little flair (optional): Once assembled, lay skewers flat on a platter and drizzle lightly with balsamic glaze and/or olive oil. Sprinkle with cracked pepper if you’d like a savory note.
Serve immediately or chill for up to 1 hour before serving.
