Oil for greasing the pan
1¼ pounds Brussels sprouts, trimmed and halved
2 tablespoons peanut oil
2 tablespoons soy sauce
1 tablespoon Dijon mustard
Heat the oven to 350°F and lightly grease a 13- by 18-inch baking sheet. Toss the Brussels sprouts with the peanut oil, soy sauce, mustard, and a little black pepper. Transfer to the greased baking sheet in an even layer and roast until the sprouts are partially tender, about 15 minutes. Stir and raise the oven temperature to 400°F. Continue to roast, stirring every 5 minutes or so, until the sprouts are browned and fully tender, 15 to 20 minutes. Serve hot or warm.
