Hi Marcia,
I avoid plastics and have gone to glass. I don't have to worry about the plastics breaking down in the food. I found some Anchor Hocking/Made in US glass... microwave, oven, fridge to freezer bowls with plastic lids. Found this particular set at Big Lots for $20.00. I wash the lids by hand so theirs no danger of misshaping.....
They also look good enough that I can serve food in so I don't have as much to wash.....
