I did lunch for 14 today and menu was potted salmon and crostini to start (BBC good food recipe - it was really easy and could be done day before it was delish too!), beef casserole with savoy cabbage and mustard mash (a la Gordon Ramsey), then nigella's English trifle for pud. It was yum!!
Something light and fresh before casserole type main:
Salad of pear, watercress, lambs lettuce, parmesan shavings and walnuts. Dijon mustard, white wine vinegar and olive oil dressing. Some nice crusty bread on the side. Assemble a couple of hours in advance and add dressing at the last minute.
