Christmas Global Buffet Ideas

I’m planning a meal for 8 people the day after Christmas. 2 vegetarians, 1 lactose intolerant, 2 non-picky kids, and 3 adventurous eaters. I wanted to do a sort of global buffet of small bites/appetizers/tapas/mezze-style options. I thought it might be fun to do classic Christmas or festive appetizers from countries around the world. I’d welcome any ideas or suggestions please. It can be meat/fish, dairy, or veggie options-the aim is to have lots of lovely choices so everyone can enjoy!
