Thanksgiving
The green bean casserole was first created in 1955 by the Campbell Soup Company.
Dorcas Reilly led the team 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 Campbells Cream of Mushroom Soup.
In 2002, Reilly presented the original recipe card to the National Inventors Hall of Fame in Akron, Ohio.

Though New England had a great abundance of wildlife and seafood, traditional East Anglian fare was preferred, even if it had to be made with New World ingredients.
Baked beans and pease porridge were everyday fare, particularly during the winter, and usually eaten with coarse, dark bread. At first it was made with a mixture of wheat and maize (corn), but after a disease called wheat rust struck in the 1660s, it was made of rye and maize, creating what has later been known as "rye 'n' injun".
Vegetables with meat boiled thoroughly was a popular dish, and unlike many other regions in North American colonies, they were cooked together, rather than separately, and frequently without seasoning.
Baking was a particular favorite of the New Englanders and was the origin of dishes today seen as quintessentially American, such as apple pie and the baked Thanksgiving turkey.
