I'm throwing a surprise birthday lunch for my mum this Saturday. It's only a few people but she's been through a lot lately so I want to go to an effort. I'd like it to be impressive, although it doesn't 'need' to be. I was thinking of roasting a side of salmon but have no idea what to serve with it. Lunch will be fairly informal and people will eat standing/sitting etc so it needs to be finger food-ish. Ideas would be most welcome.
