Texas Toast

Yield: 64 Squares. Preheat the oven to 400 degrees F. Combine the cheese, butter or margarine, pepper, and mustard in the top of a double boiler or in a heavy-bottomed saucepan. Heat until blended and smooth, stirring with a wire whisk. Meanwhile, toast the slices of bread. Spread the cheese mixture on the toasted bread, cut into quarters, and bake until browned, about 5 minutes. Note: 2 or 3 drops of Worcestershire sauce on each quarter toast will enhance the sharp "cheesy" flavor of this hors d'oeuvre. Yield: About 64 squares.
