Step 1

Heat milk in a small saucepan. Melt 1/4 cup butter in another saucepan, stir in flour and cook for 2 minutes. Whisk hot milk into flour mixture, stirring constantly until thickened, about 5 minutes.

Step 2

Add cheese, beer, tomato paste, Worcestershire and mustard and stir constantly over low heat until cheese is melted, about 3-5 minutes.

Step 3

Spread remaining butter on bread and place on broiler-proof pan or cookie sheet. Top bread with bacon, then tomato. Pour 1/2 cup cheese sauce over each bread slice. Broil until lightly browned, about 2 minutes.

Step 4

Garnish each with chopped parsley and serve, assuring diners that there are no bunnies involved.
