Once you have an idea of how to organize your fridge, consider getting a turntable for your shelves to quickly find items and keep them accessible as well as expiration dates visible. Also, if you do not have these handy already, get clear stackable containers for leftovers; this will help keep your fridge neat and organized. Lastly, keep a permanent marker close to your refrigerator to label items with the date it was opened as a reminder for how long it has been open and when to eat it by before it needs to be tossed out.
