HISTORY: (according to wiki)
The green bean casserole was first created in 1955 by theCampbell SoupCompany.Dorcas Reilly led theteam that created the recipe while working as a staff member in the home economics department. The inspiration for the dish was "to create a quick and easy recipe around two things most Americans always had on hand in the 1950s: green beans and Campbell’s Cream of Mushroom Soup."
In the 1972 version of the Good Housekeeping Cookbook the recipe replaced the creamy mushroom soup with sour cream.
