A TJ's Dumpster haul (bag included).

Thanksgiving’s upon us, and we can practically taste the stale-bread stuffing and just-expired eggnog. You too can learn how to turn refuse into a festive holiday meal by joining the Freegans of NYC tomorrow (Wednesday, Nov. 25), for their guided tour of borough’s most fruitful bins. You’ll collect some forsaken feastables and learn the best ways and means of salvaging trash treasures. Ever seen those darkly-dressed, bicycled people loitering in front of Trader Joe’s around closing? That could be you!

Not all Freegans look the Dumpster-diving part (some are quite well-dressed, indeed, coming from work and all). But all take the ideals of frugal living and elevate them to a life-philosophy. Followers of the faith refuse to spend money (either on anything or just on food) in protest of consumerism, current means of production, or simply out of necessity.

The group’s mystery tour finally will reveal just how Freegans manage to come up with everything from gourmet sandwiches and sushi to the staples of bread and milk (expiration date, schmexpiration date). Don’t worry, the experts do know how to safeguard against the dreaded parasite or two. The tour guides themselves go out every night of the week to warehouses, stores, restaurants and even private homes, to collect what often is a truly motley meal. Whether you’re on the hunt for some free Christmas gifts or for a Thanksgiving side, just make sure to bring some gloves.

Meet: Wednesday, 9 p.m. at Court St. and Montague St., in front of the TD Bank. More info here.
