Choosing just one all-plant-based meal on April 22 could make a big difference to the planet. So says Sodexo, which is asking its 10 million U.S. customers to eat low on the food chain this Earth Day.

To inspire the change, Sodexo chefs are cooking up new ways to serve the classic peanut butter and jelly combination.

Environmental advocates estimate that Sodexo’s PB&J For A Day campaign could save 1.3 billion gallons of water, 12,400 tons of carbon emissions, and about 5,500 acres of land if all of the 10 million served daily by Sodexo choose one plant-based meal.

Customers at Sodexo-served college campuses, corporate cafes, hospitals, and senior residences will be given the option to choose a plant-based protein meal on Earth Day in the fun form of creative peanut-butter and jelly cuisine. Sodexo’s Earth Day menu choices will include:

Fluffer Nutter Club Sandwich, Grilled Peanut Butter and Banana with Chocolate Chips, Toasted Peanut Butter Baguettes with Jelly Dipping Sauce, Peanut Butter Pancakes with Jelly Syrup, and for dessert customers can try the PB&J Sweet Shot or a PB&J Muffin. You can find the recipes and cooking demonstration videos online.

For this campaign, Sodexo is partnering with the PB&J Campaign, a project of Social and Environmental Entrepreneurs (SEE). The PB&J Campaign approaches positive change one meal at a time by illuminating the differences one single dining decision can make.
