When you’re making dinner, think about what you’re going to eat for lunch tomorrow. If you’re making a salad for dinner, make a little extra and put it in a container, undressed, for lunch the next day. And what about your leftovers from dinner? Is there a little extra chicken or maybe part of a can of beans? Toss that in with your lunch salad. Packing lunch is a great way to make sure you’re not wasting any leftovers—and to help you eat healthy, save money and save time throughout the day.
