So this is EXACTLY why the internet is awesome, because of tools like this one.

http://www.recipematcher.com/ [1]

You put in the ingredients you already have in your pantry/refrigerator, and they give you a list of recipes you can make with those ingredients - and highlight the items you still need.

To test it out I picked a few random things I have on hand right now:

peanut butter, Cheese - Cheddar, Chicken - Breast, canned tomatoes, olive oil,Rice - Brown

and it pulled up a bunch of recipes I only need a few more ingredients to make. This is a great way to save money! And, there's also an identical tool that asks what alcohol you have and then recommends mixed drinks you can make.

Enjoy!
