An eggs benedict eggs and Canadian bacon atop an English muffin may have been the first official, open-face breakfast sandwich, followed by the bagel with lox and cream cheese. Eggs and sausage patties or ham have found their way atop English muffins ever since (popularized by McDonald's Egg mcmuffin in the 1960s). In the 1970s, the concept evolved to the breakfast croissant sandwich, and in the 1990s, the breakfast burrito—scrambled eggs and sausage or bacon inside a tortilla wrap.
