Remove crust from bread; toast bread until lightly browned on both sides, and set aside.
Combine cheese, whipping cream, mustard, and Worcestershire sauce in a small bowl, mixing until well blended. Spread reserved toast with cheese mixture. Place toast on a 15- x 10- x 1-inch jellyroll pan; broil 4 to 5 inches from heating element just until cheese melts. Serve immediately with pickles as an accompaniment to soups or stews.
