Slab bacon, beans, coffee, onions , taters, corn meal, flour and look for greens, berries and nuts in the woods if you gottem, honey or syrup if you want sweets.
If you want sour dough bread get a recipe. Take some hooks if you got fish and a line. If you want meat take a 22 for game and its light. A single shot is my favorite because you only get one shot. It is good for rabbits, squirrels and birds and all birds are good to fair. Now the best coffee can be made with river water, use a gallon can,
with about half full of water, put in the amount of coffee you want and put it on the fire. The coffee will float till it boils when it rolls over take it off the fire. pour in about two tbsp of cold water and the grounds will settle to the bottom and that will be the best coffee you ever had. The garlic and olive oil serves for lots of purposes.
Canned corn beef if you like it and a stick of pepperoni. Check the shelf for other canned meat if you like it. Cans get heavy. I used a dutch oven, 12 inch cast iron skillet and a boiling pot(4qt) I didn't survive, or camped, I called it living. Gnewt
PS. This was for living outside and you would have to build a shelter. If it is in a home, stock up, weight will not matter, if it keeps get it. Remember if you don't use it you can trade. Especially beer, wine, booze, and cigarettes for trading, take gold.
If possible start a herd with six or 8 hens and a rooster. A billy and two nannys if you have grass and weeds. You need seed also. A few lamps and oil and a kerosene lantern.
I have lived this life in the 30's and early 40's as an ant and not the grass hopper.
