What each ingredient does

Sweet onion (in the method): Provides mild sweetness and aroma, and thin slices soften the sharp bite of raw onion.
Buttered bread: Holds the filling together and gives the sandwich its structure and a rich, toasted-butter flavour.
Mayonnaise (in the method): Adds fat and moisture, helping the filling taste rich and keeping the onion from drying out.
