This is awkward. And I apologise to any non-meateaters out there who might be offended at this thread, it's honestly not intended but is a genuine situation.
MIL and BIL came to our house for lunch on the day after Boxing Day (27th Dec). I was under strict instruction to give them "leftovers" from Christmas lunch and not to make a fuss over lunch. Technically, this would have been easy but MIL is a vegetarian who doesn't eat cheese nor "foreign food" ie stir frys or pasta. I know. it's her. She lives off Quorn sausages and chips and vitamin pills.
My own Dmother was staying with us over the Christmas period and on Boxing Day morning at 8.30 am she received a call telling her to move all her furniture upstairs as there was going to be a significant flood risk. By the time we'd all argued about whether to drive her back or not it was too late and the roads were closed due to the flood water. In the end, I took her home by train on 27th Dec, the same day as MIL and BIL came to lunch.
OK, here's the AIBU. I was planning on making a puff pastry tomato tart for lunch, with bits of feta cheese on one half for BIL and plain on the other half for MIL, together with a green salad. However, the York floods put me off my stride and I left the house without preparing anything, leaving DH in charge.
So, I come home later that night and DH tells me that he'd made his mum a salad sandwich and she'd polished off the sprouts and roast potatoes. I went bat shit BECAUSE I'D ALREADY TOLD HIM NOT TO GIVE HER THOSE TO EAT - the potatoes were cooked in duck fat and the sprouts were full of chestnuts and bacon. Apparently she wolfed them down.
And here's the really bad part. DH phoned MIL for their weekly chat and apparently she's now got this craving for meat and she doesn't know where it's come from - she's been veggie for 19 years and this is the first time she's ever been desperate for a bacon sandwich.
I don't know what to do - I feel guilty as it's our fault (up to a point, though) and it's definitely DH's fault for not listening to me - so should we tell her the truth or leave it as our secret and hope she gets over it? I do feel bad though, it wasn't done on purpose, but now 19 years of good work on her part is about to be unravelled.
