Just a thought here. Many of us keep supplies of canned tuna in reserve.
Most "experts" recommend canned tuna in water for dietary and caloric-intake reasons. However, tuna in oil, once drained, will leave you with a decent amount of cooking oil which can be used to prepare other foods.
Sardines (incredibly long shelf life) and other fish also come canned in oil.
If using canned veggies for soups, use the entire contents of the can, including the water the veggie is packed in.
