Sweet potatoes are really good for you too. I haven't seen the instant kind but I bake them and dehydrate them all the time. I have a bag in my pack right now with some pecans and dried apples. I like to add a granola mix after it hydrates and its like an apple crisp desert ... of course on the trail its just food and give me more of it.
I've got some dehydrated too. Adding the granola mix sounds good...great idea.
