chuck the liver, and rashers of bacon cut into 3 pieces, and a couple of large onions sliced, into a casserole with some water into which you have stirred some oxo gravy granules. bung it in the oven for a couple of hours. serve with mash and peas - delicious!
it will end up tough if you fry it for too long, but in a casserole it just gets more tender.
