Besides takeout, and great option for at home or on board dining is the At Home Meals from Brandywine Estate. Chef Regis make several different meals that are all frozen and serve 3-4 people. Easy to store on board and then warm thru in an oven. He has Chicken Pie, Fish Pie, Beef Lasagna, Vegetable Lasagna, Coq Au Vin, and Eggplant "something". Also a couple of soups!

I've tried several and they are very good! Available from the restaurant if you call in advance (they have moorings and a dinghy dock).
