Going vegetarian used to mean giving up all hope of making it big as a competitive eater. But contestants at the Taste of Buffalo (the city, not the mammal) eating contest will be scarfing down kale instead of hot dogs this weekend. Kale Yeah!, an apt name for the challenge, bills itself as the world’s healthiest eating championship. The winner takes home a $2,000 prize, plus the pride that comes with downing a football field’s worth of greens.
