So, back from my hike, and not too bad from a dietary stand-point. Some things were really good, others not so great. The Quinoa cereal I tried to substitute for my oatmeal was not a favorite. I don't think it gave me the energy I'm used to to start a hike from, oatmeal definitely works better for me. Not crazy about the flavor, either. I added brown sugar, Earth Balance spread, toasted pecans, dried blueberries, cranberries and cherries, with cinnamon to it, and it was ok, but not great. Dinners worked out better--I used Sarah's Cranberry Chicken with Rice one night, having found a gluten-free stock concentrate from Packitgourmet.com. That was yummy. I tried her Thai Peanut noodles, substituting home-dried rice macaroni and almond butter for the noodles and peanut butter, and adding freeze-dried chicken, spinach and carrots, and roasted cashews. Not quite as good, I think if I had used tahini along with the almond butter, or if I could have found cashew butter it might have been better, but certainly good enough to eat and get along with. I carried gluten-free peanut-free bars, homemade jerky and peanut-free trail mix for snacks, with gluten-free salami and bread for lunches. Gluten-free bread is very dry, not sure I'll do that again. I also found gluten free dehydrated black bean soup mix that makes a great dip/spread if you don't add as much water.
So, thank you all for your help during my pre-hike freak-out. 4 more weeks to go eating like this, then hopefully I'll get to at least add tomatoes back!
