I'm spending christmas alone, what's a good recipe to try?

For various reasons I'm alone at Christmas this year. I'm not down about and want to spend the time trying some new recipes.

Any suggestions for a good Christmas dinner i can make on my own?

I'm still after a nice meal and i'm thinking a small joint of roast meat (not turkey) for a main, but open to trying your favourite marinade for it and side options or a different starter or main!

bon appetit
