Sides to serve with crab legs

I'm trying to think of side dishes that would go well with crab legs at a Christmas Eve family gathering. Others are providing the crab.

In the past I've provided hor d'oeuvres like cheese, pate, savory crepes, and salads like a Nicoise. For this meal I am trying to think of finger foods (and dips) that would go well with the crab itself.
