I eat one or two a week as regular lunches, to rotate stock. When there's some room at the empty end of the shelf, I shove everything down, and buy some new cans to stuff in at the intake end.
It takes no more time than going to the pantry for a can of soup regularly would. And saves time, because I'm _never_ out and scrambling to find another option. Whether I'm 8 cans down or 24, one trip to the store will replenish it regardless.
Don't overcomplicate it. Folks who blog about things tend to do so because they're proud they achieved something difficult, so you compare yourself to a difficult standard. Resist that.
Even though the campbell's exec declared it "poor food" the jazzy jambalaya has replaced our instant pot recipe. We buy two cans of it, add a package of microwaveable ready rice and have decent (although very carb and sodium heavy) dinner in ~3 minutes.
It also cooks up great in a small pot on a pocket rocket and tastes great right of the can as far as it being suitable for emergency food.
Freeze dried stuff can be sit on a cool, dark shelf for a decade or two; a popular company:
Also need to have a source of water and a way to boil it.
Of course you’ll need a way to cook the dry food. The most sustainable way I know of is a small portable solar system and an instant pot. The instant pot is very energy efficient so you don’t need a very big solar system depending on where you live. If you store flour, you can also get a bread maker, which is pretty efficient.
The reason I like this strategy is that it’s cheap, and you don’t have to think about it very often. You can just trash the food after some number of years. You also don’t have to eat food close to its expiration date normally.
The only hiccup is fat. Cooking oil goes rancid, so you probably want to replace that every year or so, but canola/soybean oil is very cheap.
Of course none of this is very healthy, so you’ll want to include some vitamins…
Grab 2 packs of dried pasta instead of 1 for example. Rice. Beans. Canned stuff like veggies, fish, even the little single serve veg/beans etc.
Anything is better than nothing which is where most people land. Even knowing you got enough food stuffs for a day is enough comfort to ward off panic in disaster situations.
A 24/30pk of 500ml water can be had for like $5/10. Also very useful outside of disaster if they’re cycled through.
The grocery stores all had plenty of fresh food (some things ran short, but there was always plenty) I'm reasonably sure you never needed the camp stove, or any of the other supplies. They might have been nice to have anyway, but never needed.
