Toast the Bread: Place the slices of white bread in a toaster and toast until golden brown and slightly crisp.
Assemble the Sandwiches: Take two slices of the toasted white bread and spread half of the mustard on each slice. Layer the thinly sliced salami on one slice of bread and then top it with the other slice, mustard side down, to form a sandwich. Repeat for remaining sandwiches.
Serve the Meal: Serve the sandwiches alongside olives, hummus, and pita chips. Serve with cola over ice.
