Helping your kids make school lunch

This year, I'll be making 3 school lunches each day. In the past, I have only had to make one. To help streamline the process, I have created a lunch making area in one of my cupboards. I keep all of the supplies needed there. I'm hoping it will help!
I also decided that my children need to help make their own lunches. To help them understand what to put in their lunch, I made this handy little chart and hung it on the cupboard with the lunch supplies in. I'm hoping it helps them in deciding what goes into their lunch.
What are some things you do that help lunch making go smoothly?
