NEW YORK -- Dinner shared by a group of friends at a well-appointed Greenwich Village apartment featured eggplant Parmesan with a salad of mixed greens and avocado dressing. The guests already had snacked on hors d'oeuvres of smoked mozzarella and crackers. Not bad considering the diners find their food by digging through garbage. They call themselves "freegans," a play on the words "vegan"-- vegetarians who avoid all animal products, including dairy -- and "free." In an ideological rejection of consumer waste, they only eat food that's been discarded.
