Fill a martini shaker half full of ice. Add the mint and lemon peel. (I used the peel of about ¼ of a small lemon). Smash the mint, peel and ice with the handle of a wooden spoon, until the mint leaves are bruised and it's all mixed up. Add the vodka and watermelon lemonade. Shake vigorously. Strain into chilled martini glasses. Enjoy!!
