*Party rye or thinly sliced French bread can be used instead of white bread. Double recipe to have enough sausage mixture.
Preheat broiler. Crumble and cook sausage in medium skillet until browned. Drain on paper towels. Transfer sausage to small bowl; stir in cheese, sour cream, mayonnaise, green onion and Worcestershire. Cut crusts from bread. Cut each slice into 4 squares; spread about 1 teaspoon sausage mixture onto each square. Arrange squares on ungreased baking sheet; place under hot broiler just until cheese melts and topping bubbles. (Be careful not to burn corners and edges.) Serve hot.
Note
Quick Sausage Appetizers may be made ahead and refrigerated overnight or frozen up to 1 month before broiling.
