I love my Laptop Lunchbox. Packing a lunch can save you lots of money, ZenHabits posits as much as $3,000 per year. Although I understand why some folks need to go out to purchase lunch (socialization, anti-socialization, lunch meetings, etc) I prefer packing my own when I can.
The Laptop Lunchbox system is sort of American Bento. It's a box with interchangeable compartments, that divide the space up into 1 large and 2 small or 2 medium and 2 small spaces (although you can get creative about that). There is also a designated spot for utensils, and it comes with a fork and spoon. It also fits neatly in a desk drawer (or under my desk drawers). With a system like this you could make ahead several lunches and store them in the fridge (or just components) to save time. You're also helping the environment by not using single-use containers, like plastic bags
I have a nightly habit of packing my lunch as I make dinner. Although sometimes I can't help it, I try not to pack the same thing every day, so I don't get bored. Favorites are salad, leftovers or sandwiches as a main component, with apples, pears, mandarin oranges or grapes as one side and goldfish crackers or gummy fruit as a second side (OK, I do sort of eat like a kid). I also like this lunchbox because it is very helpful for portion control. On salad days I sometimes wish it was a little bigger, however, usually I pack the right amount of food for me. Since I am not my ideal weight, every little trick that helps me eat better is good!
