Roast Beef with a sweet kick.

A nice soft, but seedy bread, slightly toasted. Smear with mayo and a mustard (your choice). Layer with 2 or 3 thin slices of roast beef, a slice of Havarti cheese, 2 or 3 slices of bread and butter sandwich stackers (a single layer to cover the whole sandwich) and finally a generous stack of arugula.
