The Breakfast Jack.
A breakfast sandwich is a sandwich made with breakfast foods, commonly served on an English muffin, bagel, Kaiser roll, or buttermilk biscuit. The sandwich typically includes eggs, meat, and cheese. The American-style breakfast sandwich has been a working-class staple since the 19th century, but it wasn't until the 1970s and 1980s that it became a cultural phenomenon when fast food chains began serving breakfast.
