McDonald's, which is testing a variety of new food products as part of its turnaround effort, on Wednesday said nine southern California restaurants are trying out breakfast bowls made with what is becoming a state dietary staple: kale.
One of the breakfast bowls is made with turkey sausage, egg white, kale and spinach and the other includes chorizo and egg. Both are priced around $4, McDonald's spokeswoman Lisa McComb said.
Kale, touted as a nutrient-rich "superfood," over the last five years has been growing in popularity in the United States, both in grocery produce aisles and on restaurant menus.
McDonald's rivals Chipotle Mexican Grill and other quick-service chains such as Yum Brands' Taco Bell over the past few years have helped popularize bowls, which are typically made with meat or another protein, rice or another starch and vegetables.
Separately, Janney Capital Markets analyst Mark Kalinowski said in a client note on Wednesday that McDonald's restaurants in Canada will soon begin offering three salads made with kale as an ingredient.
