I definitely enjoy Chocolate & Zucchini, Smitten Kitchen and Orangette (mentioned above.) I also really like:
Hunter Angler Gardner Cook (
http://www.honest-food.net/blog1/) - This guy, well, hunts, fishes, gardens and is a great cook. An interesting read.
The Paupered Chef (
http://www.thepauperedchef.com/) - If nothing else, these guys show that you should just jump in and try something, even if you're not sure how it will turn out.
Very Good Taste (
http://www.verygoodtaste.co.uk/) - This is where the Omivore's Hundred originated
101 Cookbooks (
http://www.101cookbooks.com/) - This one is rather more on the whole foods/healthy/granola end of the spectrum, but the recipes are good.
