I came across this link on Facebook today, and it looks like a great resource. If you try to be pretty assiduous about keeping track of your calories, it can be really frustrating when you make the switch away from processed foods. The only thing I really miss about them is being able to get an exact calorie count per serving off the back of the box.
That's where SparkRecipes comes in. It's got a free recipe calorie counter, where all you need to do is enter the ingredients in your recipe and the number of servings it makes and it will give you a full (if somewhat approximate) breakdown of nutritional information.
Like AllRecipes, it also has many recipes submitted by users of the site, and if you register you'll be able to save recipes of your own in your "cookbook." Definitely worth checking out.
