Snacks are essential fuel for students on the tennis courts at Sportsmen’s Tennis and Enrichment Center in Dorchester. Thanks to a new collaboration between the center’s after-school program and Paulette Chandler, MD, MPH, of the Phyllis Jen Center for Primary Care, these young athletes are enjoying and learning how to prepare snacks that are tasty, healthy and easy to replicate at home.

Held as monthly events through the Brigham and Women’s Center for Community Wellness at Sportsmen’s, the classes feature interactive cooking demonstrations with local chefs and discussions about nutrition.

Students who attended the program’s December class heard about the benefits of beans, legumes and seeds—including their ease of preparation, cost-effectiveness, environmental sustainability and nutritional value—and learned from Siva Kumar, executive chef of Walnut Grille in Newton, about how to make bean-and-avocado tostados with pico de gallo.
