These Glad Containers are great for leftovers. We had 3 boys and a girl and as they got older and started moving out, one of the weirdest things to get used to was leftovers. Turns out we were continuing to cook for the same amount of people but there were just 3 of us. We went through a LOT of Tupperware type containers.
