Tinned: We keep some "fully loaded"'s in the pantry, I like Oops and Spaghetti, I always take canned corn - kernels, creamed and baby for chinese, beetroot, coconut milk/cream, soups - chicken, mushroom, tomato. You can also get tinned milk, condensed milk with or without coffee. You can buy those Meat Pies in tins as well and they are fantastic .. I prefer the mushroom one. It's endless what comes in a can.
Packets: soups, mac & cheese (I prefer home-made but The Kid loves these), uncooked - rice, noodles, spag, pasta, Aldi pasta mixes, Rice-A-Riso (add meat and veg), various 2 minute noodles. Dried vegies are always a winner when fresh stuff runs out. The peas are my favourite, I dislike Deb potato with a passion ...
I also have an extensive spice selection. I use "money" bags from the local Newsagent 100 - $5 at most, and fill those with my favourites and basics. I always have flour and yeast in the pantry. You can freeze small portions of garlic or ginger in an ice tray for vac sealing, if you don't want to risk taking bottles. A lacky band or two (or some pvc pipe at the right size) around tins and bottles stops them from rubbing together as well as marking your fridge or pantry.
I find bread, eggs, meat and veg are the only thing that we take fresh, but there are egg alternatives out there for extended trips, Mountain Bread and lavish are great bread alternatives that last well too.
