>>821429GORP. There is no better camping food than GORP.
Tastes good, it's lighweight as fuck ( standard mix should have around 500 kcal/100 gram), doesn't require any preparation whatsoever, lasts for months, lots of proteins, lots of good fats and vitamins.
You just can't beat it. If there is no GORP in your pack then you are doing something wrong.
