We have spatchcocked a chicken on BBQ before which worked well, could do that with a small turkey.
Beware pigs in blankets - bacon can be problematic due to excess grease dripping into coals/gas and flaming up. But if you have a tin foil tray to catch the grease that should help.
Could do prawns in their shells or on skewers as a nod to starters.
Peppers stuffed with some bulgar wheat and suitable spices to go with pittas/Moroccan style?
If you have warm gear and are prepared for longer cooking than summer (due to external temps cooking bbq), then go for it any enjoy!
We do a neighborhood “snowed in bbq” if there’s enough snow to cover the ground - very in exciting emptying of fridges so usually sausages, wings, maybe burgers, served with hot wine for adults and hot squash for kids so we all enjoy the outdoors together. There can be up to 3 bbqs pulled out for that from various houses.
I am contemplating, if numbers are ok and have continued to reduce locally, planning ahead for 1 on the green over Christmas but not 25th, so we can all Catch up while outdoors and SD. As our sociable street have not had any gatherings all year apart from 2 seperate “Sunday evening beer on the green” half hours in summer when numbers were low and we were allowed gather outdoors.
If we do it, everyone will bring their own food and drink, glasses and plates, chairs etc - if loans of chairs are needed, wipes will be there to use as well, and we will spread out on the football pitch sized green out front.
