Your 1st task is to learn how to cook, otherwise with your limitations on storage
, cans and refrigeration
you will be one hungry camper....other than salami the items on your staples list all require some know-how....to put together.
I hope you are a good fisherman, there are few sources of protein on your list.and you will also need to add a good source of vitamin C....
You can boil eggs peel em and pickle them....
If you don't want canned tuna...get some canned chicken meat..costcos is a good source.
Bread---find a recipe for irish soda bread...it's very easy, no yeast involved..I add raisons or craisons to mine...start to finish in 50 minutes! add baking soda to your list..
They have whole milk that requires no refrigeration..(parmalot)..you can use powdered to supplement. or get cans of sweentened condensed milk.
Oatmeal, and/or dry cereal...like a granola with dried fruit and nuts...again costcos has a good one.
There are many varieties of rice and grains..bring a few.....basmati, Rissoto, cous cous, cracked wheat etc...get them in plastic containers with screw on lids.
I might bring some corn grits....or I call it polenta..
A piece of salt
cod might be worthwhile..some cured ham..
Peanut butter..had been mentioned!
dried..packaged soups....or soup bases...the commercial
variety comes in smallish plastic jars...Chicken, Beef, vegetable, mushroom, lobster bases are all available.
use them as a base for soups or...as stock for cooking your rice in.
Pastina...ditalini...in addition to regular pastas...make good soup or stew additives.
lemon, limes, grapefruit..as long as they'll hold up..
Some aged dry cheese..
I always carry some white clam sauce..and linguini..
There are lots of good pickled items...that will store well..
Keep all your dry beans..rice, flour, baking ingredients in good airtight containers...moisture is the enemy.
