A rolling information display apparatus configured to rotate on the rolling surfaces of a roller grill is provided. The apparatus includes a tubular shaped body configured to roll in contact with the rolling surfaces of a roller grill. The apparatus further includes a calibrated cook timer, a temperature monitor, a temperature indicator, and an information medium removably positioned on the tubular shaped body. The calibrated cook timer includes a printed circuit board that is calibrated to rise in temperature in a similar manner to a food item that is cooked on said roller grill.
