I don't know - I read this and think that maybe it's more than about cooking.
It seems like it's more about appreciation.
Hoggie, you work some really long hours, and I'm sure that you would likely like your wife to show that she cares about the sacrifice you make and that she cares about you by seeing that you have something nice to eat when you come home. If that's true, have you ever articulated that to her?
And Mrs. Hoggie - she likely wants appreciation too. Maybe she doesn't really like the hours that you work, since she has to manage all mealtimes and kids on her own, and she may have to cook two meals - one for the kids earlier, one for you later.
So....what to do?
Well, have you discussed this with her? What are her complaints about it?
Can some be resolved by doing something simple - like employing the use of a slow cooker (my personal favorite cooking item) so that both kids and you have a decent meal and still only a single meal cooked - and you don't need to do anything more than throw a few things in a pot and turn it on?
Is there any way to restructure your work time? How much time do you get to spend with your wife and kids?
Do you praise her or show appreciation when she does put in an effort to cook? You do get more when you use honey rather than vinegar.
