Slices of bread in sandwich bags, then in the bread bag.
It takes us a long time to go through a loaf of bread. Because of this, I remove the individual slices from the bread bag and put them, two at a time, into sandwich bags. I then put them back into the bread bag, then into the freezer. This makes the bread last longer in the freezer, a lot longer! And when we want to make a sandwich, the sandwich bag is already there.
