Book excerpt: Imagine going to the supermarket and buying three bags full of food but then dropping one in the parking lot before driving away. With the amount of food we waste, it's like we all do the equivalent of that every single week. In fact, forty percent of food is wasted in North America. When you drop leftovers into the household trash or even the compost bin, not only are you emptying your wallet, you are also contributing to global warming. It's time to get smarter about sustainable consumerism. With more than 140 recipes organized by ingredient and countless brilliant ideas for using everything up,The Waste Not, Want Not Cookbook will show you how to shop, cook, and eat and zero waste. You'll learn how to transform leftovers into delicious new dishes, how to store and preserve foods to make them last, how to shop smart when buying in bulk, and interpret "best-before" dates. You'll even learn how to cook once and create three different meals. So heed the wisdom of your grandparents and reclaim the contents of your fridge.
