An omelette is the ultimate frugal dish: the way it’s possible to transform a couple of eggs, a pinch of salt and a tablespoon of butter into a delicious meal is truly rewarding. Fantastic plain, an omelette is also the perfect vehicle for flavourings and fillings — sweet or savoury. A sprinkling of fresh herbs, a filling of grated cheese or sautéed vegetables is all you need. Also, try making a thin, one-egg omelette (add 1 teaspoon water to the beaten egg), slice into narrow strips and serve on top of oriental soups, rice and noodle dishes.
