Oh my goodness, yes OP totally with you! It's definitely the mental side of it more than the actual cooking. I can sense the question coming and dread it if I haven't planned something. Working out something that everyone will eat, that's healthy, tasty and provides al the nutrients everyone with their various activities need, something that will eb fine to reheat if we are eating at different times.
Even if I plan it all out at the weekend and buy all the ingredients ready to cook, inevitably someone throws a curve ball in and food gets wasted, un eaten or un made: husbands shifts changes, a child has a sleepover or eats at an activity. I don't understand how strict meal planners do it and don't have any waste? Does everything go in the freezer? De-frosting things properly and timely is a pain in the arse too.
What makes it worse right now is I am trying to lose wait so I am actually batch cooking smaller meals for myself, mainly with rice (2 out of 3 of my family don't really like rice) so the evening meal is mostly just for them, I'm not even eating it!
1 night maybe 2 a week I just don't bother, see if the husband bothers to think about it, 99% of the time never does, so the kids end up with a pot noodle, omelette or a cheese toasty they rustled up themselves and then I feel massively guilty that it is unhealthy (maybe not the omelette)! Then I think I should really teach them how to cook, but then there is the stress of doing that, and how much can a 12 and 14 year old do for themselves without chopping a finger off or burning the house down. Ugh.
