What is everything? It's an interesting question. Funny since we often talk about giving everything we have. An everything pizza does not contain everything nor does the everything bagel. Sometimes the term means whatever is necessary to achieve an ideal and bountiful balance. A burger on a bun is not an everything burger. It is what it says it is. A burger with bacon, guacamole, cheddar, pickled jalapenos, lettuce, tomato, onions and smoked ketchup for the fries may well fit the bill as an everything burger. (Could we really fit anything else on it.) In any case, the term everything is often as diluted as it is all encompassing.
