There isn't just one. There are many recipe sites that provide this function. You can even utilize major search engines like Google to refine your search. Just read the Advanced Search tutorial on how to include words, and phrases you want and omit the ingredients you don't want.
If you want to stick to a recipe site only, then try the following which are just a few among thousands and type in the ingredients you want:
Allrecipes.com
http://allrecipes.com/Search/Ingredients...
Marthastewart.com
http://www.marthastewart.com/recipe-find...
Epicurious.com
http://www.epicurious.com/recipesmenus/a...
I was going to say no but I looked at the other answers and saw I was wrong.
Try www.cooking.com, and here on Yahoo! there is a food link you can add to your toolbar.
