I did away with nuking in plastics altogether a couple years ago. Of course the glass containers have plastic lids but I never use the lids in the microwave. I use mostly my copper coated skillets and mostly glass in the oven also except my copper coated cookie sheets. My sister on the other hand is stil using plastic in the microwave and they've seen better days, all pitted on the interior side but she's hard to make changes of any sort. I don't think I have any pans witht he teflon coating any longer either.
