I just discovered via this lovely little blog that I read, a website called SuperCook!
You enter in the ingredients that you have, and it searches the web to come up with recipes that have only those ingredients! I just did a quick glance over our pantry and fridge, entered in a bunch of stuff and it came up with over 2000 recipes!! You can store the ingredients list so that you only have to enter staples like flour, sugar, soy sauce, etc. one time. You can also enter exceptions (things you don't want the recipes to contain). How cool!! This would work great for weeks like this one where I have promised not to go to the grocery store and to use up some stuff that we already have. Check it out!
