Thanks for posting this thread, I was about to post something similar, because I'm considering thru-hiking next year without maildrops, and I'm interested in good stuff you can make from what you can buy on (near) the trail.
During a thru-hike with no maildrops, I don't think I will have access to gourmet stores, online or otherwise.
Also I won't have a home to go back to, so these recipes with the preliminary "prepare at home" or "dehydrate at home" steps in them won't work for me.
So I'm interested in recipes using only ingredients you can get from small groceries/convenience stores in little towns along the way. I have not seen much in the way of "dehydrated vegetables" in such stores.
