We’ve all done it. Brought home the leftovers from that restaurant meal (portions are so big), only to throw them out two weeks later. Or perhaps you don’t like bringing home leftovers at all, but just hate to waste all that food. Or maybe you ordered a pizza and realize that you can’t possibly finish it yourself. Now a new app, Leftover Swap, allows you to share your leftover food with others nearby. The brainchild of Dan Newman and Bryan Summersett, and drawing inspiration from Tristram Stuart, Newman explains “Besides the 40% of food we waste, there is 16% of the American population without enough food to live a healthy lifestyle, which is mind boggling.”
