I thankfully don't have any food allergies but am a cooking fanatic who is trying to eat more healthily. So, here are a couple of sites that have great information and recipes.
The woman that writes this first blog lives here in my hometown. I don't know her personally, but a friend of mine does and says she is constantly developing new recipes and sharing the results with her. My friend said everything she has tried has been wonderful!

Hope this is a help! :P
