Beef-and-Brussels Sprouts Stir-fry
A ripping-hot skillet works as well as a wok to sear food fast. Just be sure to use one that can take the heat, preferably cast-iron or a large, heavy-bottomed stainless. Feel free to substitute any cruciferous vegetable cut into even pieces in place of Brussels sprouts, from broccoli and cauliflower to cabbage and bok choy.
