In another thread, someone mentioned a recipe website (now I can't remember who, which thread, or which site!), and I know there are some lists on 3FC, too. I use cookinglight.com a lot. You can put in an ingredient and it brings up a whole list of recipes and includes nutritional content like fiber, fat, and other things. Plus there are reader ratings, which I find really useful.
Are there other recipe websites that people use? I wouldn't mind bookmarking a few.
