How many times have you dug into the fridge to find something to snack on or to hunt for the tub of butter or just to clean it out and found a bowl of mystery food growing in a long forgotten corner? Or wanted some leftover that you thought was in there but now you can't find it?
No one wants to find fur developing in their fridge because they forgot they had put some leftover casserole in there! So, one way to solve this problem is to keep a running leftover list on your fridge. Below is a picture of ours. We use a very small dry erase board (we got ours free from the Realtor when we moved into our current rental but I have also gotten them from a baby expo, a competition my husband was in during high school, and I've seen them at Goodwill and Wal*Mart.) You can also just use a piece of paper stuck to the fridge!
Any time you put a new leftover in there, add it to the list. When you use something up, mark it off or erase it. Mine is fairly simple (unless I have been doing a lot of cooking and have lots of leftovers.) You can also do like my Mom does and write the date of when the item was put into the fridge so you know when it needs to be used up. You could also put how many (approximately) portions are left.
There has been more than once that I have used a leftover side dish for dinner the next day, saving me from making a whole other side dish. It is quick, easy and saves you from digging for that little container of beef stew that you think is in there when really it was eaten by your hubby at 2 in the morning the night before. :o)
