Beanie-wienes, pork and beans, potted meat, viennia sausages, Spam and tuna in the small foil packages, and a loaf of bread, are staples in my food box. Along with small packets of mayo, mustard, and ketchup(bought by the case at Sam's club). When I took teens along I also carried cans of Beefaroni and Ravaoli.
The small cans of green beans and cream style corn, help supplament the fresh meat we often eat, while hunting Moose and Caribou. We often shoot Grouse and Ptarmigan as well, that these canned vegies compliment.
