Hi T - Happy Christmas -
Spaetzle, braised red cabbage and apfelkren (apple and horseradish) sauce if you want to be all Austrain about it.
If not, slice nicely and serve with celery, avocado (for some more fat in the diet..) green leaves, walnuts, green peppers, a good french dressing and some proper warm bread.
Make some rillettes and serve up on warm baguette with some green leaves as a filling snack.
Mrs Beeton says make a goose hash...:

Simply carve and serve with a creamy mash - potato and carrot; turnip; celeriac; bubble and squeak....and a good acid fruit sauce like rhubarb and champagne; gooseberry; kumquat and cognac, etc etc with a fresh green side as well.
Devilled goose with rice, salad and a couple of sides like avocado and chili salsa and amango pickle...
Classic British - serve with a Cumberland Sauce...
Make potted goose - or if you're posh, a pate....
and boil the bones up and get the bits going for a good stock.....
Hope that helps some.
