One night your kids are asking for seconds; the next week when you make the exact same dish, they leave half of it on the plate. So chances are you have random leftovers that are getting lost in your fridge, like a chicken breast or a couple spoonfuls of beans. While there probably isn't enough for your family to have the meal again, you can use these little bits and pieces as part of another dinner -- and free up your time and grocery budget in the process. Just two things to remember: "Nearly all leftovers will last three to four days as long as you get them into the fridge within two hours of cooking," says Pat Kendall, PhD, RD, professor of food science and human nutrition at Colorado State University in Fort Collins. "And for safety reasons, you need to reheat the food to steaming hot before serving." So get your leftovers out of cold storage with five healthy recipes the kids will rave about.
