Feeding the 5,000 is a program, part of the European organization FeedBack that is tackling hunger in a specific way – using food that would normally be wasted. They work to glean crops from farms that would be wasted also but host public events to bring awareness to this issue. They explain it this way "At each event, we serve up a delicious communal feast for 5000 people made entirely out of food that would otherwise have been wasted, bringing together a coalition of organizations that offer the solutions to food waste, raising the issue up the political agenda and inspiring new local initiatives against food waste."
An example is an event that took place in Vancouver, Canada on May 27, 2015.
It was grassroots “lunch and learn” on a grand scale. Everything on the menu came from industry donors. Those attending got a tasty free 3 course lunch, an appreciation of food waste in the region, connections with those already taking action to reduce waste, as well as ideas for reducing food waste in their own lives. Here is a video.
