This is about me and my meals though. My family is getting ripped off when I spend a sum of money on food that isn't very good. I've spent $40/person for meals that were as good as I could make at home in an hour, even though I'd be saving money doing the work myself it was still wroth it because I didn't feel like cooking.
If my neighbors decide that the meals they can buy are good enough that is their choice. I won't enforce "my good taste" on them. I find the value is not there.
Your second point is, basically, that you like the work (on meal prep). But that is completely besides that point.
The way you should look at this is: would you agree to serve meals for $12 for a neighboor's family of 4? And I bet the answer is no, you would not.
