Roast, uncovered, for 35 minutes. Add cauliflower to pan or dish; sprinkle lightly with salt and toss to coat. If chicken is browning to fast, cover loosely with foil. Roast another 25 to 35 minutes or until an instant-read thermometer registers 170°F. in the breast or 180°F. in the thigh and cauliflower is tender, stirring cauliflower once more during cooking.
