But it doesn’t sound fun. And you’re not sure what “better” means, anyway.

You’re in luck—welcome to Veganuary, your free, monthlong, all-inclusive intro to plant-based eating.

Started last year in the UK, Veganuary is the brainchild of two animal-loving advocates who realize January is when we’re most likely to make positive changes. Their website veganuary.com encourages you to take a monthlong vegan pledge and gives you everything you need to succeed—recipes from rock-star vegan chefs, nutrition basics (yes, vegans get plenty of protein), dining-out strategies and menu options.

Yet followers of the Standard American Diet (note the acronym, SAD) still ask, “What do I eat if I don’t eat meat?” Cheer up—being vegan means giving up meat and dairy but keeping the pleasure. It turns out many of your favorite brand-name foods and drinks are vegan. They always have been. Check out PETA’s list of “accidentally vegan” foods at peta.org/living/food/acciden tally-vegan.

We’re talking Kraft Taco Bell Taco Dinner (14.9 ounces, $3.09), Pepperidge Farm puff pastry sheets and shells (17.3 ounces, $3.75), Kellogg’s Pop-Tarts, blueberry and strawberry, unfrosted (14.7 ounces, $2.55), Red Bull (contains caffeine and glucose but no bull or any other animal) (8.4 ounces, $2.19) and dozens more, most available at your favorite supermarket. Caveat: Just because they’re plant-based doesn’t mean they qualify as health food or will help whittle the waistline (think Doritos and Oreos). For that, both Veganuary and PETA’s websites offer plenty of produce-packed recipes of every ethnicity and cuisine.

Traditionally, people go vegan for three reasons—personal health, protecting the environment and saving animals.

Now there’s a fourth—vegan is tilting from fringey to fab, with more (and more delicious) vegan foods available in stores and restaurants, and the likes of John Salley, Jared Leto and Ellen (another vegan, the rich, blonde, famous one) on board. It’s so hot, Bill Gates has invested some of his bazillions in vegan food startups.

Veganuary lets you in the club, too. So try it for a month. Take the pledge, pass the Pop-Tarts and have a happy, healthy Veganuary.
