I would go for a nice salad, asparagus, salmon with a few veg, potatoes or rice, cheese, some nice fruit with really high quality ice cream (I'm thinking grren and black's organic vanilla - yummy) for those who want it.
I'm not fond of making a big deal of desert, can make people feel forced to have it even if they don't want to (and there's no such thing as a sophisticated and quick and easy desert imo)
