Teenagers in Aspen, Colo., have eaten meatless meals in schools every Monday for about two years now. In fact, so much of the entire city has embraced the Meatless Monday movement that Aspen has been selected as “the nation’s first true Meatless Monday Community,” according to the folks at MM headquarters. In a city with the lowest obesity rates in the nation, many hospitals, schools and organizations go meatless on Mondays. Meatless is offered up in many restaurants as well, but those catering primarily to tourists sometimes face a challenge with the pesky carnivores.
