On Friday I got a secondhand copy of Delia's Christmas (its praises were being sung on here the other week) and I've now made a bunch of her savoury scones and palmiers to freeze for when DH's family come over on Boxing Day. We'll have some salami and stuff as well so what I'm lacking is stuff that is a bit lighter or contains any vegetables at all. What would you all suggest for vegetable-based canapes?
