Our family relies a lot on frozen Tilapia that can be fried up easily enough in a non-stick. It isn't rocket since, 7 hours is an exaggeration (for the USA at least), but...there is surely a better way to do this food preparation thing (outsource to businesses who can scale up and specialize in it, like we did in Roman times).
Yes, that is the problem with the USA. But surely there must be some room for disruption here: food that can be prepared more economically than you could by yourself. It has happened in other countries (even Switzerland has lots of nice cafeterias that are very competitive with home preparation), why not here?
