Let me start by saying I can cook pretty well, and have cooked for large numbers at Christmas ( all from scratch), this year it will be us 4 and pil, and I am tempted, well more than tempted to get it all ready done at M&S or Waitrose - out of sheer laziness. Lovely pils won't care, but I am feeling guilty already looking at my full basket online. What to do ? Votes please.
