This Skinny Peach Frozen Margarita is Summer in a glass! I love the bright flavor of a delicious Peach Margarita, but lightened up in Skinny Margarita form. This cocktail is made with simple ingredients such as frozen peaches, peach sparkling water, agave nectar, lime juice, and of course, Tequila! There's no better way to celebrate Summer than with these perfect fruity Frozen Margaritas!
