Ok, nothing else posted here so I'll bite
I keep a large amount of store bought goods on hand, most them to help with my personal brand of "scratch" cooking.
I find a can of cream of mushroom or chicken soup can be made into a kings meal by adding some rice, beef, potatoes, beans, taco meat or chicken most of the time.
My most favorite pheasant is a can of cream of mushroom soup poured over a dressed pheasant and bake for an hour.
Really it isn't any harder than that.
Or take 3 different kinds of canned beans and put them in with a half an onion, a green pepper and a pound of meat and you have chili fit for a king (don't forget a tbs of chili powder)
Or can of cream of chicken soup, can of green beans, and some French fried onions (maybe some pepper or some garlic) and bake for an hour.
Haha as I was googling some other examples I found this

A canishborg of easy to make meals on the cheap.
Ok that being said you need to shop around for your soup. If you go to wallmart right now you can easily pay $1.75 for a can of condensed soup. But if you pay attention and watch for a sale you can get them below $.80 cents on sale not only at wall mart but the Sams and Costco venues.
I always keep about 48 cans of each of the soups in stock and when we use 6 of them I start shopping around and restock, rotating my larder and making really tasty dishes at the same time.
Most of the dishes listed above is a great meal or side dish for $2-3, (I usually put in harvested elk so it may be more where you live)
My point is this
SHTF
Put in 1 cat, 1 raccoon, 1 squirrel, 1 can of cream of mushroom soup, half an onion, dash of pepper and garlic, bake for 1 hour...... the best tasting scratch cooked meal you have ever had... Really!
