Pass a piece of roasted beef, cold or at room temperature, through a food processor or meat grinder. Mix in some onion and green olives without pits, stirring well. Season with Worcestershire sauce, salt, lemon juice, and a pinch of pepper, if desired. If the beef is difficult to pass through the machine, add a little oil, butter, or margarine. Serve on slices of bread as desired.
