McDonald's is rolling out some changes to its burgers. PEOPLE reports the buns for all of Mickey D's hamburgers are being revamps. Also, McDonald's will add onions to the burgers while on the grill to bring out more flavor. You can also expect more Mac special sauce on your Big Mac which will make a lot of people happy. Some of these changes to the burgers have already been made in Canada, Australia and Belgium. The U.S. West Coast is getting a taste of the reimagined sandwiches first and then the entire country should get their new McDonald's burgers by 2024.
