I just ran across a great website that you plug in all of the items you have in your Refrigerator and Cupboard and it will list recipes to make with your items! This helped me out last night when I was at bare minimum for food until I went shopping today.
It also gave me a great apple cinnamon recipe that I never would have thought of for a snack for the kids.
This is a great way to save money than going to the store because you "think" you do not have anything in the house to make for dinner.
ETA: The original site posted is no longer functional, but Super Cook is available: http://supercook.com
Does anyone use any other tools or apps for cooking from your pantry or cupboards?
