We've got a couple of sets of friends (with smallish children) coming for lunch between now and New Year. Want to make a bit of an effort, but conscious that we will all have overeaten over Christmas, so nothing too heavy. But don't want to go too basic (e.g. soup, bread, cheese (which is what we would be eating without guests) either. Roasts and anything turkey related definitely out! Any ideas? Will be cooking for 8 on both occasions.
