OP it all sounds lovely - I am a complete foodie and always cook from scratch but I don't get too hung up about it when camping.
We tend to camp off the beaten track - if I can buy locally I will but if I can't I can usually manage for a week. We have a child with very severe allergies and over the years I have become used to not being able to rely on buying things when I am away
Risottos are good camping food, I freeze chicken in little pieces before I go, a piece of parmesan is fine in a plastic container a week. Saffron and white wine make another lovely risotto when the frozen/cold things have been used up if you can't get to a shop.
I freeze things from my lovely butcher for a BBQ for a couple of nights and usually use those the first and third night when the salads are still fresh.
We also do 'Look at what I found' a couple of nights (curries are best imo), you can buy direct from them, much cheaper - I ordered last week and got 15% off and free delivery - I got 34 packets of various things for £54. Sell by dates are 12 months from now. We camp a lot - will probably have been for 50 nights this year when we stop at the end of October. I reckon we will still be using food from this order when we get going again in the spring. I usually add something like peppers to the curries. Things like naan can be longer life ones.
I also like to have Merchant Gourmet cooked grains/lentils and those packets of flavoured cous cous in my food boxes when camping. A tin of butter beans and tomatoes cooked with a stock cube and a few herbs make a lovely soup with a carrot and a bit of garlic and parmesan.
Have you thought of a pressure cooker OP? Great for things like Irish Stew in about 45-55 mins (I always take the other bits with me from home), depending on what you can buy locally.
The other thing to think about is how often you open your cool box. We have the swanky one with the frozen things (usually still frozen on day 5), another one for fruit and veg and a small one for the day. It really makes a difference to how long things stay cold if you have the room.
Have a lovely holiday - whatever you eat will be fab.
