Making meals for my family usually leaves me with leftovers. I use my stock pile of Cool Whip bowls to keep the leftovers in the fridge. I can also write what's inside on the lid or the side. When my son or daughter leave with their families, they can have some leftovers too as a treat for their next day. They can recycle or throw the containers away after eating their food. Hopefully by reusing these containers it will show my grownup children that they can reuse or recycle too. I also use the Cool Whip bowls as containers to freeze food too. They work great and they stack really well.
