My own mum usually looks after dd on a Thursday and Friday, but she is on holiday, so MIL is staying overnight tonight to look after dd.
Dh and I eat lots of pasta meals, but MIL only likes very plain food. When we go to her house, she generally cooks a joint, with accompanying vegetables.
I do not really have time to cook a joint, so what can I buy at the supermarket today that I can cook tonight when I get in from work.
I realise this is quite a vague brief. She doesn't like any 'foreign' food.
