I've posted it a bunch of times but if you go to The World's Healthiest Foods -a really good resource that'll give you more info than you ever wanted to know about pretty much every vitamin and mineral known to man... including sources of it...
whfoods.com is one of my favourite websites for nutrition! I love how they break down every vitamin and mineral in the foods. I've yet to try any of the recipes, I should give something a whirl one night.
