This is one of Urban Gleaners’ year-round free markets, where all are welcome to fill a bag with a wide variety of donated food. This culinary alchemy plays a significant role in Urban Gleaners’ outreach and fundraising. Urban Gleaners plans to reach even more people during its annual Summer Supper on Sept. 15 at The Redd in Portland. Niebes recalls that while she enjoyed the gala dinner, “we wanted more people to see what we do, so we changed our large summer supper to a festival-style event. But it also keeps nearly expired food out of the landfill and makes good use of it.”Urban Gleaners' Summer SupperSeptember 14, 5-8 p.m.831 S.E.
