I often make nasi goreng as a storecupboard heavy meal - but it could be completely storecupboard if you wanted.
Normally, I use leftover cooked rice (from the day before or that I have frozen), leftover cooked chicken, frozen or fresh prawns, an onion, garlic, carrot, mushrooms (whatever other veggies need using up that work in stir fry type dishes), frozen peas, tin tuna, small tin corn, curry powder.
Carrot, onion and garlic are all long life veg that don't need a fridge. A pepper will certainly last a few days outside the fridge but maybe not a week, mushrooms for a shorter time. A sachet of microwave rice does work well. As well as tinned tuna and corn, tinned prawns are fine (I've used those a few times). (I often use the tinned tuna in oil, and drain the oil into the pan to use for cooking the dish as an extra dash of flavour and thriftiness combined). And curry powder.
Packets of dried pasta with powdered sauce (like Knorr Pastaria, and others) are light weight but useful. They only need to add water and perhaps a nob of butter for richness, as long as you have a cooking ring to use. I sometimes toss in things like diced salami to add some interest (cured meats are preserved to not need refrigeration like raw or cooked meats do, so could be used for later in the week).
Others have mentioned couscous which only needs boiling water and seasoning, but no direct cooking involved.
I've made camping pancakes in a plastic milk carton before, weighing out the dry ingredients at home and marking where the milk should come to on the bottle - pour the milk in to the bottle when on camp, put the lid on and shake well, then pour onto the pan. You could experiment with using dried milk powder in the mix, so you only need to add water.
Eggs also last well without a fridge. French toast is a great breakfast meal when camping if you have bread, and it can be as the loaf is getting a little stale. But eggs are very very versatile generally.
Also, in terms of your camping trip, check with the site in advance as they may have a small shop onsite or close by to get some fresh items during the week.
