Sweet potato hash with pork and kale

Sounds like a pretty wholesome meal to me. It can certainly be served on its own. But if you want to pair it with something, you can look into mulled wine or other drinks you have in your household.
Or you can pair it with sour dough slices, any other bread available for you is fine too.
Also, you can make a simple tomato sauce pasta topped with cheese if you prefer a hearty meal.

So, you want Christmas dinner ideas, which our first suggestions didn’t give you.
I hope others here will come up with some more ideas, more in that direction.
