It is an American icon and today it celebrates it’s 40th birthday. I had no idea I was a mere 2 years younger than this McDonald’s classic and though I don’t eat them often now I certainly grew up with them. Invented by McDonalds’ franchisee Jim Delligatti in 1967, today is it’s 40th birthday. I always remember, “two all-beef patties, special sauce, lettuce, cheese, pickles, onions on a sesame seed bun.”
