Barely a recipe at all, but jolly useful when one is cooking only for oneself, and nobody is watching.
Get a deep pan or a wok going on the heat, add a couple of glugs of vegetable oil, and slip in a 200g piece of rump steak. I don’t particularly care how you do it, whether it gets thirty seconds a side in an incandescently hot wok, or whether you prefer the low and slow approach. Whatever. The end result should be a piece of meat with some nice colour on the outside, and still fairly squidgy when you poke it with an implement: this and this alone is the key to working out whether or not the meat is done. It should be less soft than the raw steak, but by no means hard. Retrieve it from the heat and pop it on a chopping board to rest.
Turn up the heat in the wok, and throw in 300g of stir fry vegetables; whatever you fancy. Stir like mad until they’ve softened up and are starting to colour. Turn the heat down, and add a splash of soy sauce and a generous squirt of sweet chilli sauce. If you’ve yet to make the acquaintance of the latter, then I warn you: it is addictive.
Meanwhile, turn your attention to the steak, and slice it thinly, trimming any bits of fat and gristle that you don’t fancy. I use a chopping board with a rim to catch the juices. Return the steak and juices to the wok, give a good stir, and then serve.
