On one hand you are absolutely correct stating that swiss restaurants are in general more expensive than anywhere (subjective - e.g. a 30$ small menu might be ok here, but we do have as well a higher income and going to the restaurant is not something that people do often), but on the other hand I did like airline food (which you basically describe as being "the worst" while for me was on par with one offered by restaurants), therefore we have a mismatch of our experiences.
(talking about restaurants, I must mention that Stockholm was for me a lot more expensive than Zurich)
Personally, I would have all kind of doubts about a $5 meal (in most parts of the world, if it's not something extremely simple).
> There are meal-delivery services here that are basically what you describe, but they usually deliver food weekly and they're kind of pricey. They're mainly targeting time-strapped single people who are trying to eat healthier and don't want to do all the mental work that goes into grocery shopping, meal prepping, cooking, etc.
I'm not currently aware of something like that in my area , but my profile is very similar (and I did try to cook different stuff, but the failure rate is quite high and the overall quality quite low). Still, I think that the concept that I described was a bit different than that?
