Bubble and Squeak
Chop lightly with a knife in a dish any cold greens and potatoes you may have left. Melt in an enamelled frying pan one ounce more or less of fresh butter. Turn the vegetables into it. While cooking use a large dinner fork to press the vegetables into a smooth paste, turning it over and over with the fork all the time to prevent it sticking to the pan. Vegetables so treated should work into a perfectly smooth, stiff paste and leave the pan as clean as when they went into it. Add a little pepper and salt.
Be careful to remove all stumps of cabbage before using.
