Repurpose the leftovers from an event -- without throwing any food away.
Next time you attend or host a potluck, BBQ, picnic, or any event with food, make a personal commitment not to allow anything edible to go in a trash can at the end of the event. Leftovers can be great for casseroles, soups, and even just reheating the next day. Or, if what's left over doesn't fit your dietary needs, find a good home for it with others. Leftover food is perfect for composting, too, so try not to put even what's gone bad in the hot sun into a trash can!
Wasted food not only contributes to hunger, it clutters landfills and contributes to climate change. Meat especially has a high carbon footprint; when wasted, that's carbon spent for nothing.
