How about quiche? With jacket potatoes and salad? It's my fail safe with families coming to lunch, because it can all be prepared in advance, most kids eat jacket potatoes even if they don't fancy the quiche.
Individual Fish Pies, bake a potato, cut off top, scoop out centre, mix with some fish/herbs/cremefraiche/cheese, refill skins and bake into oven to reheat, I saw this idea in Olive magazine a couple of months back an have been dying to try it out! :D
Chicken Pies?? You can go the whole hog and make it all from scratch or use that pie filling and ready roll, a big one or individual ones. Plus if you mix in some herbs or stilton, no one will even quibble about the pie filling :D
