I'd guess it includes the bread and meat, no cheese, no condiments - definitely no mayo. Probaby no black olives, but the lettuce, spinach, tomato, green pepper, onion, cucumber contain few calories anyway. The wheat bread option gets you some fiber and more vitamins. Toasting doesn't change the calories! Mustard isn't many calories either.
