How do you store your leftovers? Because I do not like storing warm leftovers in plastic, I’ve found mason jars to be a fantastic way to store and reheat leftovers in the microwave. And did you know it’s also great to write the date on the lid so you know when to throw out leftovers? I use a sharpie marker and date it as I am filling the jar. Just a little dab of toothpaste will remove the last date and prepare you for your next filling 
Mason jars are green, BPA safe, frugal and an excellent way to see your leftovers in the fridge. They are especially great to see the leftovers and not forget them.
Did you know you can purchase mason jars at Goodwill for.25? I’ve also seen them at garage and yard sales, thrift stores and free on Craigslist. The wide mouth ones are easier to fill, but regular ones work just as well. Finally, measuring cups make jar filling so easy to pour the contents right in. Pint or half quart size jars can hold lunch leftovers and/or salads and transport easily. By the way, check out how I use mason jars for my pantry organization here.
I’m just a frugal, earth-friendly, freezer cooking advocate. I hope you enjoy this kitchen tip and try it soon! Or perhaps you’ve been using them all along.
