, this is the site for light and tasty magazine though they changed the name again.
has some good light recipes that use foods we have around the house normally.
has a ton of stuff and usually you can scale the recipe to the size you need.
I collect cookbooks so when I feel I am in a rut I browse through my collection to get ideas but I have also been known to browse the cookbook section at our library. They have lots of ones that I don't have at home.
Oh yea, and I browse the South Beach, Low Carb, and WW recipe forums for ideas too. I have found several interesting recipes posted there.
