I've just worked out my basic Christmas Day menu and Asda shopping order:
Breakfast: Lidl protein roll split and lightly toasted, topped with cream cheese and smoked salmon. Champagne or Prosecco. Possibly a high meat content chipolata or two because we've got guests that day who might not like my breakfast - its up to them.
Lunch: Prosecco and maybe a touch of nice red. Maybe a few nuts to keep me going - selection of brazils, walnuts, pecans, hazlenuts and macadamias.
Christmas Dinner: Big plate of rib of beef served with a selection of veg - choice of brussel sprouts, maybe a roast baby parsnip roasted in goosefat, steamed brussel sprouts, a couple of little carrots (chantenay?) sauteed in butter, roasted cauli+broccoli+baby fennel, roasted whole garlic bulbs, runner beans, red wine gravy and (if I feel deprived) one Delia Smith recipe Yorkshire Pudding. (I have to cook these because husband, guests and dogs will feel deprived if I don't.) Red wine
Dessert (an hour or so after dinner): Home made low carb Baked New York style lemon cheesecake
Prosecco
More Prosecco
Nibbles: Brazil nuts dipped in good chocolate, home made fresh cream brandy or jack daniels or rum truffles (or all three), home made coffee and walnut fudge. I'm not the worlds greatest for making sweets 'n' sweet things but I'm going to have a go cos Christmas wouldn't be Christmas for me without some truffles.
Yet more Prosecco
Supper (if required) Home baked ham, loads and loads of different cheeses, pigs in blankets, cuke & celery to dip in to pate, . I am experimenting with a no added sugar cranberry sauce to go with the ham.
Even more Prosecco
Boxing Day:
Brunch: Eggs, Bacon, low carb chipolatas (no Prosecco for breakfast today

)
Dinner: Roast garlic and herb chicken served very warm (not hot) with loads of salady stuff and ham and cheeses and pate
Supper: As Christmas Day.
I really don't feel that I will be missing out on anything. There will be other more carby stuff available for those that want it such as goosefat roast spuds, Christmas pud, mince pies, brandy butter, bread and a mountain of normal sweets - but from remembering how I felt last Christmas (and the one before that) I really don't think I'll have any because I never want to feel like that again.
