Love to take photos of your meals? Why not turn your Instagram love into a donation to help fight hunger? The free app Feedie connects to your existing social networks. When you visit a restaurant that participates with Feedie and take a picture of your meal, that restaurant then donates money equal to a meal. World-renowned chefs like Jamie Oliver and Mario Batali support the Feedie app, and so far, over 12 million meals have been donated.
