My kids take bread rolls to school for lunch so I buy a lot every week and freeze. before freezing, I cut them in half so all I need to do is to take out what I need and fill them with whatever I'm using WHILE THEY ARE STILL FROZEN. Then I put them inside the (clean) inner bag from an empty cereal box, seal them tightly with the plastic closure thingy from a loaf of sliced bread and put them in the fridge the night before. Voila! Ready to pop into lunch boxes the next morning. They don't dry out, stay fresh and I'm recycling all at the same time! I also save so much time in the mornings!
