I think the inspiration for this little brainstorm was the book, Confessions of an Organized Housewife (which book, by the way, caused my friend Lisa to about die with laughter when she spotted it on my shelf, half hidden behind a flower vase, three hair barrettes, and an old disposable camera, while helping me pack for the move).
The author of that book talks about kitchen organization, and storing items commonly used together in one place, instead of, say, measuring cups in cabinet X and measuring spoons in drawer Y. Makes more sense to keep your measuring cups and spoons together along with the electric beaters, your favorite mixing bowl, and possibly the baking powder.
I thought that was a great idea and promptly took her advice (some six or seven years ago).
Later it occurred to me to use that grouping technique for the lunch-prep items my kids and I use almost every single day. I got a plastic basket for the pantry, and that's where we keep the peanut butter (creamy and crunchy), honey, and a loaf of bread. It's much easier to pull out that one basket than to have the kids rummaging through the pantry for the various items.
Hardly rocket science, but it works for us!
(And of course this is the same principle at work in my famed Personal Salad Bar.)
