"Chips and guac with a margarita quite simply symbolize vacation and relaxation to me," says nutritionist and author Keri Glassman, who offers a lighter take on the dish for PEOPLE.com readers. "This Cinco de Mayo, I'll probably make guac and chips at home with my kids and enjoy a margarita on the rocks while they sip homemade lime slushies."
As for the recipe, which incorporates nonfat Greek yogurt and reduces the amount of avocados, Glassman explains: "By using fewer avocados than usual and adding yogurt, we reduce the fat but keep all the avocado flavor and creaminess."
She has written three books – most recently Slim Calm Sexy Diet – and shares what she calls her "whole person approach to health and wellness" as a frequent guest on the Today show, The View, Dr. Oz, among other programs.
"Cucumber, onion, tomato, bell pepper, and garlic are all low in calories and packed with powerful phytonutrients," she tells PEOPLE. "All these veggies add volume without calories, so even a large helping of this guacamole doesn’t push you over the boarder!"
Plus, they're in season!
But, says Glassman, if you can't find peaches, or want to change things up even more, you can substitute mango or papaya.
