I woulda thought that “progressive burger” was definitely an oxymoron, but I do believe “Kale Burger” would put the lie to that idea. With ideas like the Kale Burgers who needs to worry about what competitors are doing. McDonalds, welcome to six MORE consecutive quarters of falling sales!
I don't think progressives should like a kale burger, since kale was promoted in this country by Benjamin Franklin and Thomas Jefferson. They'd probably like a, "living, breathing," burger.
