DH won't eat the same meal twice in one week. I, personally think it's absolutely bonkers, but apparently MIL never did (I must verify this with her!) and he doesn't like it. Fine. I've got used to it. However, usually during the week, I cook for the DC and will e.g. make a double portion of lunch which we eat 2 days later.
This week I made a massive lasagne. Plan: Monday lunch, Wednesday lunch when DH is home office and then we'd finish the rest Thursday lunch. Except DH has now decided he's working from home today (as well as yesterday). I don't have any other food in apart from eggs which he doesn't like. Else I can make an emergency pasta & tomato sauce - which is basically same as the lasagne!
So AIBU to serve him the lasagne? I'd planned to do the weekly shop tomorrow, going today will inconvenience me next week (even though I'm a sahm).
