My suggestoon for you OP!
Dear Husband
You already know that you will be catering for xx amount of people, so this is just a helpful reminder list to remind you of what people expect to eat on Christmas Day and Boxing Day. Of course most people should, and will be happy with whatever their host is kind enough to give them. However Christmas IS different. These people that we care about very much (or we wouldn't have invited them to share such a special time with us) will have grown up with an expectation, maybe even a need, to have Christmas as close to the way that they celebrate it as possible. With xx amount of people coming we can't possibly even try to meet all their expectations, so the nearest we can do is attempt to emulate the typical TV British Christmas. So for:
Christmas Morning (no cooking & tweaked to account for special diets etc)
A buffet breakfast that they can help themselves too. I will help you lay it out:
Sliced thick cut bread, Muesli, Cornflakes, Weetabix, Coco Pops (or similar, as a treat for Children), contintal pastries, Toaster (clean - no crumbs), butter at room temperature, strawberry conserve, marmalade, 1 other conserve, Fresh fruit, Bowls, side plates, knives, spoons, T-spoons, Glasses, Mugs for hot drinks, sugar, granulated Sweetner, Chilled Orange juice, Chilled water, Chilled Semi-skimmed milk (but any other dietry milks needed should be readily abailable in the fridge), Champagne or Prosecco, T bags, Coffee (not instant if possible).
Soft drinks to be availabe all day.
Drinks: hot, soft, sherry, more sparkly wine?
Nibbles: nuts, dried fruits, pretzels
Christmas Dinner:
Main Course - no starter needed.
Turkey (it will be big as for xx amount of people, so time accordingly to be served at 1.30pm), Cooked Ham (or to preference) another main if needed for special requirements.
Pigs in blankets, Roast Potatoes, Roast Parsnips, Boiled Carrots, Boiled Sprouts, Boiled Potatoes - then mashed, 2 differnt types of Stuffing (not cooked in Turkey),
Bread sauce, Cranberry Sauce, Turkey gravy.
Vegetarian gravy if anyone is a vegetarian.
Wines, (beer if necessary), water and soft drinks to accompany dinner.
Puddings:
Christmas Pudding

Obvioulsly OP you change to suit your family and budget. But please don't let him get away with his choices of something really simply like Pizzas, or not only will your guests be didappointed, but he won't learn anything at all. I would give him your version of my list above (or you can just copy & paste mine!), today, so that he has time to think about it and apologise to you profusely, befote he takes it on. But if he does accept the challenge he can't then change it last minute, and if on the Day he begs you for help, make sure he puts it in writing with a massive apology. If you both decide to go through with the challenge please don't feel sorry for him, and help him where he would not have helped you.
