Once the barbecue is preheated, open the lid and brush the cooking grills clean. Adjust the control knob(s) to one notch greater than medium for direct cooking over medium-high heat.
Lightly coat the onion and potato rounds with oil and season with salt and pepper, turning gently to coat all sides. Barbecue the onions and potatoes over direct medium-high heat, with the lid closed, until tender, 10 minutes, turning once. Remove from the barbecue.
