According to the USDA, 30-40 percent of the food supply. Americans end up throwing away $640 worth of food per year in every household on average. Why not save a ton of money and use up all those leftover ingredients or freeze them for future use?
We are all guilty of wasting food, but it doesn’t have to be that way. By simply strategizing how you’re going to use any leftover ingredients, you’ll have more money in the bank and feel good about using up everything you buy.
“I’m frugal. I’m not a very acquisitive woman. I never waste food. If you prepare your own food, you engage with the world; it tastes alive.”

What about those recipes that you only use the yolk? Here are some ideas on what to do with only the egg whites:

Make sure you date the bag.
