Adolf Hitler and Joseph Goebbels share a meal on "One Pot Sunday.

 Adolf Hitler and Joseph Goebbels share a meal on "One Pot Sunday." One Sunday a month, Germans were called upon to eat a one pot meal and contribute their grocery savings to public charities.

 The pot is in the foreground of this photograph.

 Events such as One Pot Sunday were designed to reinforce communal cohesiveness. The traditional German Sunday meal after church was a glazed roast accompanied by potatoes.

As part of the Eintopfsonntag (one-pot sunday) campaign, from 1933 the Nazi Party made a midday Sunday eintopf obligatory on some days: in particular as part of the Winterhilfe, the first Sunday of the month from October until March was declared Eintopfsonntag.

The Nazi Party's official sanction of one-pot meals popularized not only traditional German stews, but Pilafs, chowders, soups, and "macaroni Milanese", the ancestor of Mac&Cheese. These have remained popular to today.

This picture is an example of Adolf Hitler's public support of the campaign, he did not participate privately. By 1937 it was internationally known that he was a vegetarian, and had been for some time.

 Eintopf meals can be made meatless, but are usually based on beef broth and contain pork or beef. Hitler briefly went through a phase in the 1930s where he held the belief that cooked food caused cancer.
