If you happen to have onions on hand (which you should, as Easter is arriving soon and you're going to need those onion skins to color your Easter eggs, Armenian style -- see Marash Girl's post on coloring Easter eggs), just chop up some onions, saute them with a bit of butter and olive oil, add sliced up mushrooms (especially if you have oyster mushrooms on hand, their fluted caps resemble a fan, and they are slightly denser in texture and don't exude a lot of moisture when sautéed), thinly sliced steak, saute a bit more, and there you have it -- three ingredients, three textures, three minutes stir frying . . . lunch for a king (or queen, as the case may be). Served with good bread, it can't be beat!
P.S. For added texture, thinly slice a few water chestnuts and add them to the mix! Oh, and don't forget the salt and pepper!
