Fish, besides catfish, bass, and crappie aren't cheap or easy to get here, so I ignore things like paella (which I love, done right), since it's not reasonable for me to cook here, and the article is about poverty foods.
I don't buy biscuits, because they are expensive, and I can whip up a recipe for 2 biscuits about as fast as I can open tinned biscuits. I do sometimes use bisquick (if it's on hand) for dumplings.
Do what works, is affordable, and tastes good. I'm not a snob about food. ;)
