Blend watermelon with the juice of two limes and agave nectar.
In a stainless steel shaker, add an ounce of tequila, two ounces of the sweet watermelon lime juice, and shake.
Fill your margarita glasses with ice, pour the margs over ice, and garnish with a sprig of mint and maybe an extra slice of lime. Or, maybe garnish with a slice of watermelon. ENJOY & drink responsibly!
