I use a super light weight Esbit Stove
and my main food is oatmeal and dried blueberries that I put into the boiling water at the same time and make sure you have salt and put a little into all meals and drinks your body needs it to replenish the salt lost when you perspire I back this up with energy/granola bars.
If I am able to shoot a grouse/rabbit I'll boil it in the same pot that I use for the oatmeal this pot has holes so I can slip a long wire handle into it and hang it over a fire the Esbit stove isn't for this type of cooking it doesn't generate enough heat.
Drinks = I bring tea bags and once again use the same pot that I cook the oatmeal in don't need the added weight of a cup.
A trick when using the Esbit stove is to either wrap it with tinfoil or dig a little hole and lower the stove in so the fuel cells are out of the wind and your pot is almost touching the ground. (I use both methods)
