My cooking is very different on a short trip than a long trip.

Very different in hot weather or cold weather. Cold weather am more inclined to want hot filling meals. Hot weather, less likely to carry anything that is very perishable. And if it may go below freezing, that limits use of liquids in cans or bottles.

Very different if I can re-supply at grocery stores every few days instead of weeks. Might even buy some salad mixes if practical.

I quit using liquid fuel stoves on trips when I fly there, only butane mix on such trips. Too much hassle to get a stove and fuel bottles prepped for airline security.

Inclined to put more effort in if there are more in the group than one.

So, not much here for suggestions as there are way too many variables, there is no generic cooking plan.

That said, someone recently asked me about food planning and prep on longer trips where you may go a long time between grocery stores, my response was oriented towards solo camping and was at this post:
will bike weight make a difference to an old guy like me?

A side note: I used to buy Mountain House Breakfast Skillet breakfasts in number 10 cans, can held 10 servings and was about 25 oz of food. Mountain house now puts 15 oz in the same sized can. I think it highly unlikely that I will be buying any more cans of that since they are charging the same price or more, but give you about 40 percent less in the can.
