M&S ready meals are pretty good to be fair!
That is all my last housemate used to eat as he thought because it was M&S and like £5 a pack it was pretty much gourmet, they always smelt awful to me.
He even thought he ate better than me, because my girlfriend would buy the fresh ingredients for our meal from Aldi or equivalent cheap but perfectly fine supermarket

If I am home alone I usually have soup, a quick stir fry or frozen left-overs.
