Check out the amazing drawings this DAD does for his kids' lunches. Awesome.
Lunchbox Cupboard: the kids pack their lunches... pick one from each drawer (fruit, granola bars, snacks, desserts, drinks) The parent chooses what goes in the drawer, but the child learns to make their own choice of what to eat. *I need to remember this! ;) Would be good with main portion chosen by parent
Second Chance to Dream: Back to School Sandwich-less Lunch Ideas
Family living site Disney Family Fun shows us how to repurpose an empty milk jug into a lunch container by washing it out, drawing lines as shown in the photo, cutting it out, folding, and attaching a hook and loop closure. This container is perfectly sized for a sandwich and a few carrot sticks or grapes. If you don't want to use this for food it also makes a clever gift box for small items.
