Soup - more specifically I'd like to recommend
Campbell's Condensed Cream Of
Mushroom Soup, a tin of which is a wonderful thing to have in the
cupboard.
The Lizard's Lazy Lunch
The instructions on the soup
tin advise diluting it with a cans-worth of water; this is not only wrong, it is downright
cowardly.
The correct technique is to mix it with a cans-worth of Semi-skimmed milk (or half-milk/half-water if you're a wuss), then very gently heat (stirring continuously) in a saucepan, and don't let it boil (it'll go all icky if it does).
While heating, prepare some toast (I suggest 4 thick slices of fresh-ish Granary bread), which should be toasted until fairly dark and crunchy, before being buttered liberally and cut into soldiers.
Garnish soup with ground pepper (to taste) and fresh parsley (in the highly unlikely event that you have some to hand*).
Eat (optionally straight from saucepan if v.lazy).
Wash bowl, spoon, plate and saucepan immediately after eating (the soup's a bugger to get off the saucepan if you leave it to dry), and return to whatever geeky task you were doing before spending 3 minutes off making lunch.
Footnote: The above dish is equally yummy if you substitute Campbell's Condensed Cream Of Tomato soup instead (although, of course I hate tomatoes) - a soup also favoured by the late Andy Warhol - he only painted those cans because had loads lying around after following my lunch recipe.
(* let's face it, if you had those sorts of nice fresh things lying around the house you wouldn't be eating toast & soup, would you?)
