What each ingredient does

Thin slices of buttered toast: Gives the sandwich firm structure that holds the layered fillings together.
Cooked bacon: Adds salty, savoury fat and a smoky, meaty flavour.
Cold chicken: Supplies the main protein and the bulk of the filling.
Mayonnaise dressing: Adds fat and moisture, and its richness carries flavour through the sandwich.
Lettuce leaf: Adds crisp, fresh texture that contrasts with the softer layers.
