Cooking over a wood fire is an art, and a royal pain even when you learn the art. Soot is hard to get off cookware, and it is really easy to spill your chow into the fire when improvising pot supports, and packing a stable grill to cook over is heavy and gets soot on other stuff.
Google “pepsi can stove” for a simple alcohol fueled stove you can make from a couple of soda cans and a bit of fiberglass insulation. It may take you 5-6 attempts to get one that works well, but that will still run you under a buck probably. They weigh very little, the fuel is much lighter and less expensive than liquefied gas fuels, and safer than white gasoline. You can use an evian type water bottle to cary the denatured alcohol for fuel, and the lid is a good way to measure it out.
If you really want to cook over wood fire, google “Sierra stove”, orthis
First determine your water situation for the area you will be in. If you need to pack water, you can’t go too far and dried foods save you no weight. Also you will not want to do much if any dishwashing. If Brackish or questionably safe water is available, I like the MiOx pen for killing bugs in drinking water, with iodine tabs as a backup if the battery in the MiOx dies. You can boil water, but that is slow and takes extra fuel.
Lightweight Food you can get way cheaper at grocery store than buying from Sporting good store (Repackage in ziplock freezer bags.):
Dried cereal of all kinds, both hot and cold. Can be bulky, but it is light.
Pancake mix or Bisquick.
Raman Noodles. Can be used in place of Spaghetti.
Nuts are pretty dense source of protein and carbs . Beware of too much salt.
Hash browns in those milk carton things.
You will need a big pot, but popcorn is fun. The jiffy-pop foil things are a waste IMO.
Dried coffee, tea, gatoraid. I take ground coffee and single cup Milita filter funnel.
Non-dried foods that are still good for packing:
Canned meat: Mix with raman for quick fill-me-up with little work.
Sardines, kippered herring, Develed ham, tuna, salmon, crab, chicken, spam…lots of choices.
Canned beef stew or chili. Yummy but only if I would have to pack water otherwise.
Flour Tortillas as bread. Try taking regular bread and enjoy your wheat-wads ™ in camp.
Peanut butter, jelly, and butter, packed in the plastic toothpaste tube things they sell in the camping store.
Eggs in the paper box they come in, cut in half, inside a ziplock bag. Empty carton makes good fire starter.
Deli Bacon can be OK without refrigeration for a while, as can most lunch meat. Hard Salami is great.
produce that pack well and do OK with no refridgeration: cabbage, carrots, apples, oranges, jicama. If you are very careful, fresh Avacado is a real treat. Easy to bruise though. Bananas are right out!
Stuff that is too easy to forget:
-Can opener: P-38 or P-51 types weigh nothing. Take two.
-Cheap, thin plastic cutting board. ("counter saver"style) Makes good, clean place to set food stuff even if no cutting is needed.
-Some sort of cooking oil. Butter can work in a pinch, but canola oil is good. Repackage some from your home pantry in small bottle from camping store.
-Salt, pepper, other spices. Dried chopped onion is great, as is garlic powder. Good way to make basics far more palatable.
-Something to turn pancakes with.
One pot that will boil enough water to be useful, but is shallow enough work as fry pan.
Take quite a bit of foil. You can cook/bake stuff in it, or use it as a lid for pot, or as a wind shield for your pepsi-can stove.
Take some glad-ware containers. Pack your dry stuff in them, and you can eat out of them, or use them for cooking or leftovers. After breakfast, you can put boiling water and dry raman in one, wrap it up in a sweater, and have warm raman for lunch without getting your stove out.
If you take some heavy stuff, plan to eat it early in trip, so you don’t carry it the full time. Dinty Moore beef stew is excellent for first night, because I like to get as far as possible the first day, and not stop to cook.
