Chop up any cold meat and mix it with minced bacon and onion. Add half as much boiled haricot beans, which should be rubbed through a sieve, and sufficient stock to moisten the whole. Flavor with pepper, salt, parsley, thyme, marjoram, and a little nutmeg, and place in a dish, covering the whole thickly with breadcrumbs. Bake for half an hour and serve with tomato sauce.
