I absolutely love having friends over any time of the day or night. I dont like to stand on ceremony however and I completely prefer an informal sort of scene where everyone grabs a drink and conversation and traffic flow seamlessly from room to room... and spills outside if its a beautiful day.
And non-fussy food fits perfectly in that scheme of things. Take these Fig-Walnut-Brie Canapes for example. Simple ingredients, perfect fusion of tastes. And done in 30 minutes.
