Sensitivity to Nightshades

I have been seeing a naturopathic physician for several years now. One of the first things this doctor had me do was a detoxification with a hypoallergenic diet, followed by several weeks of food challenges to find my sensitivities. While I intend to do it again, because I know things can change, I already know that I have a sensitivity to nightshades. While I have known this for several years, it has only been in the past few months that I have been religious about cutting them out of my diet and have noticed marked improvement in my digestion, so I know that I still have a sensitivity to them.

When I signed up for the Enlita program and started exploring the menus, I found that there are quite a lot of nightshades included in the recipes. This is definitely going to be a problem for me. I cannot eat tomatos, potatoes, red or green peppers, hot peppers, eggplant, or any other nightshade plants. Based on the research that I have done about this condition, I don't think that I am all that rare in having a sensitivity to these plant foods.

So my questions are how can I modify the menus and recipes to avoid these foods, and what about other people who might also have a sensitivity to these foods when they are still included in the plan?
