Factory workers in East London in the 19th century are credited with being
the first people to ever consume a breakfast sandwich before the invention of the sandwich.
A bap, also known as a soft roll, was a type of roll that was filled with fried eggs, meats, and cheese on occasion.
However, breakfast sandwiches did not completely reach our dietary mainstream until a little bit later, due to the fast food business.
It wasn't until the Industrial Revolution that it began to gain popularity in the United States,
It's possible that the first breakfast sandwich ever made was a combination of egg, meat,
and cheese that was placed on an English muffin and presented by the Jack-in-the-Box chain in 1969.
