I make curried lentils then dehydrate them, as standard pack fare. One time I went to an area I thought allowed stoves, then discovered it did not. I was amazed to discover my curried lentils rehydrated to perfection in about a minute, with no stove at all. Truly "stove optional" food.
On further experimentation I found the lentils were perfectly edible without rehydration at all, just in their dehydrated form. A little unusual, but no complaints.
