Camping food.

It depends what your wife likes eating... here's ideas (ignore the rubbish ones, hopefully some of these help someone)

couscous with stock, soaked dried mushrooms and peas or tinned veggies (and maybe bacon on day 1) and a smidge of margarine. Directions: Soak veggies if needed; boil water as per pack instructions for couscous (i think it's a cup boiled water per cup dry couscous?) And add a stock cube per cup of couscous. Mix veggies and couscous in largish pot; Pour boiling water and stock over couscous and allow to stand for two minutes. Add margarine, mix well, enjoy

Fried rice: garlic, onion, chopped veggies or tin of such, (?spam,) rice, soy sauce

Hot dogs with tinned frankfurts and maybe lettuce for greenery

Cook some pasta, mix through soaked dried / tinned veggies and gravox made to pack instructions possibly with diced spam. Or a tin/jar of sauce if you aren't carrying everything in a pack

Light lunch/snack: Crackers with hard cheese and salami, maybe flavoured tinned tuna, maybe sundried tomatoes or olives if you can find small canned pack (hard and waxed cheeses cope ok fir a few days as long as they don't get hot as such)

Pancakes from just-add-water mix (to avoid taking eggs milk etc) with lemon juice/sugar, other usual toppings

Cheat Shepherd's pie: harvest tin or 2 + instant mash potato

Tuna mornay made with a big tin of pink salmon (yeah I know that's not tuna. Lol)

Soup from tin or shelf-store pouch - add handful/s of 'real' pasta rather than using the ones with tiny bits of over processed noodles in them

Minestrone from scratch: half a bag of pasta, 1xtinned beans, 2x tinned tomato, bay leaves(maybe), 2-3 stock cubes, (red wine), whatever other veggies you have on hand, salt and pepper. NB definitely use tinned beans, dried ones take way too long to soak and cook on a camp stove. Combine ingreds and cook until pasta is done

Toasted sandwiches filled with tinned spaghetti or tuna, cheese slices, or harvest tins (as a kid we had a cast iron jaffle iron my parents put over a gas burner or fire). Also if you're strange like us, marshmallows and banana melt for a dessert filling (beware the melted marshmallow gets burning hot!)

If you can light a fire, don't forget damper and smores(I know they're American, but chocolate!!1!!11)

Dessert: angel whip or custard powder made to pack directions, with possible tinned fruit

I'm scratching my head wondering what I couldn't cook with a camp oven/fry pan on coals or gas, did it lots when I was a kid. 

Cheese - you could cover it in wax, use hard cheeses. Remember they were originally made to preserve milk.
Milk - Condensed milk/powdered, UHT
Eggs - no issue
Vegs - fresh a few days np.  Spuds much longer.  Canned if longer
Meat - canned or even jerky - Rehydrating link
Cooking Fats - Butter a couple of weeks out of the fridge [air tight container], margarine a bit longer, olive oil can be used in their place and lasts a couple of years.

If you're going camping why not cook a mix of 'camping' food such as
- spuds in foil on coals.  I prefer washed and skinned, though as you like, put in foil, add butter [fats] and herbs [Italian/sage] wrap and throw in the coals. 
- damper again in coals. 

Then cook up whatever else you do well. 

Bring... or make a table with your bushskills, very useful when camping and not eating in and with dirt.

So thinking muesli with milk powder and boiling water for breakfast, maybe pancakes on one of the mornings.
Omelette (2-3 eggs, onion, red capsicum, some baby spinach, salt and pepper) cooked either on open fire with BBQ grill/flat plate stand thingo or on a butane stove with a small frypan for lunch.
Then do a a simple pasta, sauce and a couple boiled veges one night and maybe baked potatoes another.

Throw in some back country freeze dried meals, couple canned stews, baked beans and tinned tuna just in case. And some flour to make damper and then I'll secretly pack peanut butter, nutella, jam as a bit of a surprise for the little woman.
