When I was a kid, my mom used to pack my lunch sandwich in tin foil. I always wondered why as I saw all the other kids with plastic sandwich bags. Now that I'm a mom, I understand. And, I've added one other twist that keeps the sandwich moist.
Tin foil keeps a sandwich's shape. It makes it harder for the sandwich to become squished by other foods in the lunch box. It also keeps the sandwich cooler for longer - which is a plus if you have a child who likes cold cuts and mayo. Before I wrap my child's sandwich in tin foil, I wrap the sandwich in a napkin first. It keeps the sandwich bread moist and also provides a built in napkin for clean up after the meal.
Wrapping in tinfoil also provides a slick surface for adding stickers or a quick note in waterproof marker.
Moms, what are your lunch packing secrets?
