Chicago | McDonald's has thrown down the gauntlet in the chicken sandwich and plant-based burger wars.
The fast food giant, the world's largest burger chain, on Monday US time announced it will introduce a crispy chicken sandwich early next year, doing battle with the popular poultry offerings at Chick-fil-A and Popeye's. It also said it is developing its own plant-based category, called McPlant, starting with a faux meat burger next year.
