Allergy difficulties

I think by now most of you already know, but figured I would post anyway. We found out that Allison has several food allergies. We knew that she was allergic to dairy because everytime we had anything from that category (sour cream, milk, cream cheese, etc.) she would break out in hives everywhere it touched. But we had no idea just how many foods she is allergic to. Wednesday she went to the allergist to discuss the results and how to proceed. Although it was a great appointment I am now feeling at a loss. Her list is very extensive. Wheat, dairy, soy, peanuts, tree nuts, eggs, oats, barley. I know that there are many places out there that have ideas and recipes, but I am having a hard time finding any that encompasse ALL of her allergies and not just some. It is pretty hard to eliminate all of those from recipes. So if you have any ideas or suggestions, websites you know about, anything at all let me know.
