I've been through a few diagnoses including Multiple Chemical Sensitivites and Fibromyalgia. Unless I get too exhausted to cook, I've never been that much into processed foods. Hopefully, I get my cooling vest soon and will be able to complete my car camping cooking set up maybe even go camping in warmer weather. Basically, it's a hollowed out tool stool (Freight Harbor) with my stove, nested cookwear, and a silicon spatula inside, maybe a mug, and a pillow attached to the seat. I'm sewing a hinge bag with zipper organizer pockets and back of the seat car organizers (used for other things besides cooking equipment). I use garden hooks to hang things on like skillets, spatulas, or my lantern to see by while cooking at night.
Except for discovering that I could make egg free cornbread (8 inch) by adding about 1/4 teaspoon extra xanthan gum, the cooking ideas aren't original. Some homemade mixes are courtesty of Bette Hagman (The Gluten-Free Gourmet Cooks Fast and Healthy). The idea for milling your own wheat-free gruel comes from Ray Jardine (Beyond Backpacking). I adapted thermos cooking to make steel cut oat porridge (like a mini crock pot) overnight and soak beans. I bought an 8 inch cast iron skillet and topper from a civil war reenactor who told me that I could use that to bake in instead of a larger dutch oven. We're planning a few weeks of travelling, and I'm thinking of getting an outback oven (

I picked up an very inexpensive food dehydrator that cooks my veggies at too high a temperature, so I don't use it that often, but I have some non raw food recipes food dehydrator recipes that I can post if anyone is interested. The Excalibur site has a lot of food dehydrator information.
