I hate those round metal containers with the clear plastic lids that restaurants give you for take home. When I get those and open them at home, I can never that plastic lid back on. I decided to start putting the whole bottom part of the container in a gallon ziplock bag. It works great!

When you have leftovers and put them away, put them in the container you plan to heat them up in.  If it’s going to be heated for individual servings, use individual containers, if it’s going to be a large meal re-heat, and you’re going to use the microwave, put it in your microwave containers,  if you’re going to reheat in the pot on the stove, put it away in the pot if you have room in the fridge. Save time by not doing extra containers!
