 The sandwich is often served as a breakfast item with coffee.
 BEC is sometimes used as an acronym for the sandwich, as is BE&C.
 McDonald's Egg McMuffin is a popular commercial version.

 The viscountcy is used as the courtesy title by the heir apparent to the earldom.
 A member of the prominent Montagu family, Lord Sandwich was the son of Sir Sidney Montagu, youngest brother of Henry Montagu, 1st Earl of Manchester (from whom the Dukes of Manchester descend), and Edward Montagu, 1st Baron Montagu of Boughton (from whom the Dukes of Montagu descended).

A Gatsby is a South African submarine sandwich typically sold as a foot-long sandwich sliced into four portions.
 It is a popular sandwich in the Western Cape province, with many fast food and takeaway restaurants, stores and food stands purveying them.
 One large sandwich may be shared among several people.
 The Gatsby is also sometimes mistakenly referred to by the nickname AK47, which is a variant of the sandwich made in Johannesburg, in part due to how it can be held in one's arm in a similar manner to the firearm.
 It has been described as a "filling, budget meal", a standard menu item in Cape Town corner stores, and as a significant part of the heritage and a cultural symbol of Cape Flats, where it originated from.
Breville is an Australian manufacturer and marketer of small home appliances, founded in Melbourne in 1932.
 They created the original sandwich toaster.
 The product was a huge success upon its launch in Australia in 1974, selling 400,000 units in its first year and making the Breville brand a household name in Australia.
 Soon after, the Breville toasted sandwich maker was launched in New Zealand and Great Britain where it met with similar success.
 The name became synonymous with such devices - to the point where in some countries "Breville" has become the generic word for a sandwich toaster, and often the toasted sandwich itself, in much the same way that "The Hoover Company" is associated with the vacuum cleaner.
