Christmas Eve is my prep-day, so we usually have a take-away.
Christmas Day, we'll be having croissants and pain-au-chocolate from breakfast, then the full works (turkey, stuffing, pigs in blankets, stuffing and sausagemeat loaf, roast and mashed potatoes, sprouts, carrots, parsnips, cauli cheese, bread sauce and proper gravy) - there's just the 3 of us this year, so we'll eat a little later than usual (around 4pm) and other than nibbly bits, that will see us through the day!.
Boxing Day will be left-overs! We LOVE the left-overs - I have to cook the main dinner with left-overs in mind!
