Begin by preparing your ingredients. Cut the watermelon and feta cheese into 1-inch cubes and rinse the blueberries under cold water.
Take a skewer and thread one cube of watermelon onto it, followed by a cube of feta cheese, and then a blueberry. Repeat this pattern until the skewer is filled, leaving some space at the end for handling.
Continue assembling the skewers until all ingredients are used. You can create a pattern of watermelon, feta, and blueberries or mix them up as you prefer.
Once all skewers are assembled, sprinkle the chopped mint leaves over them for added flavor.
If desired, drizzle balsamic glaze over the skewers for a touch of sweetness and tang.
Serve immediately or refrigerate for up to 1 hour before serving for a refreshing treat.
