i would agree with Outward Max on the vigo brand dried packets. red beans and rice, black beans and rice, santa fe, etc. the packets barely weigh anything and if you're packing really light, all you need is a little oil (and some fish). each packet easily serves three hungry campers (or two really hungry campers) and only costs 1.39! perfect pack-in camp food.

i make my own dehyrated meals for camping
usually consiting of roma's, peppers, mushrooms(morels this year)onions,and/or leeks,basamati rice(bad spelling),and a few jalapenos or one habanero pepper and of course garlic.
ill also take chicken bulion and vegatable bulion cubes and grind them up to mix with it all.
the amount of all this depends on days gone X beer or liquor X people X amount of foot travel.
then i just bring along a light(aluminum) dutch oven and oil.
add fish if its been a good day if not its good by itself.

Vigo products are great. The oil is optional. One trick since it is not fast cook (also a fantastic trick for pasta, real oatmeal, or anything else that you are supposed to simmer for a long time) is to create a pot cozy.

Basically, a pot cozy is anything you can use to insulate around your pot. Mine is an old closed cell foam pad that I cut to size around my post and then made a round bottom and top. I just get whatever I'm cooking up to a boil and then get a lid on it and throw it in a cozy. Sit back, turn the stove off and do NOT check on it until it is time for it to be ready. With the Vigo stuff, let it sit for 20 minutes and it will still be too hot to eat without blowing on when you open it up.

Advantages of a cozy:
Less Fuel
No Stirring
Nothing gets burnt to the bottom of your pan ever
