I use the small rectangle food storage containers without theirs lids as side door organizers for those extra salad dressing, ketchup, mayo, mustard and jelly that you get with takeout food. Instead of tossing them out, why not organize them in the side door of your refrigerator. Think of the money you will save. You can ask for two salad dressing packs and have one for your next individual salad. Also neat for packable lunches!
