Soups are the obvious place to start for those thus in domestic goddess mode. Soups, of course, are some of the quickest meals that you can make. Somehow the home-made soup, lovingly prepared in advance, is no longer popular. I think it comes down to stock: our disinclination to make it from scratch, together with our disdain for cubes. It is important to stress that even though the better a stock the better a soup, it does not follow that no good soup, no superlatively good soup, can be made with stock cubes. Naturally, it depends on the kind of soup: no consommé or delicate broth should be made with anything but home-made stock; but a hearty vegetable soup can, frankly, be made with water; and in between these two extremes, use stock cubes. I am keen on the Knorr Italian ones or bouillon powder (the ones made by a company disconcertingly called Marigold. But if you want to make your own stock, please refer to here for instructions.
