MCDONALD'S NEW PLANT-BASED MENU ITEM: NON-CHICKEN MCNUGGETS

During the wider market test starting in March, customers can order the doughnuts inside the restaurant, at the drive-thru and with McDelivery and its app, according to the business. The McDonald's app and McDelivery weren't options previously.

"The expanded test will help us learn more around operational impact on a larger scale as well as gaze customer demand," McDonald's said.
