Precook and freeze your proteins. Can even do this with the eggs. Will take the necessary stove requirements down to almost nothing. I managed to eat gourmet meals in the woods for a week this way using just my camp stove. When I say camp stove, I mean a stove that fits into a small pan and runs on white gas. ie, here I am making some donuts in the woods for the family
Heating up sous vide chicken tacos
Making pancakes with wild picked berries
3 minute fry on sous vide breakfast sausage
It was SUPER easy. Before the sous vide I did it all fresh. Now I sous vide and freeze our meals and just have to flash fry them. I do a lot with a pan in the fire as well. As for what you should do, again it needs to come down to exactly what you plan to make and then I can tell you what I'd do.
