Kentucky Hot Brown Sandwich

In honor of our very own Kevin Hickman returning to his home state, Kentucky, to run a marathon, we found a famous Kentucky tradition: Hot brown sandwiches with turkey, bacon, cheddar cheese, and sliced tomato and other ingredients.  Run Kevin run!
Ingredients:
2 tablespoons butter
1/4 cup all-purpose flour
2 cups milk
1/4 teaspoon salt
1/2 teaspoon Worcestershire sauce
1/4 cup grated sharp Cheddar cheese
1/4 cup grated Parmesan cheese
1 pound cooked turkey, thinly sliced
8 slices toast, crusts trimmed
4 slices tomato
8 strips bacon, cooked
1/2 cup Parmesan cheese
Preparation:
Melt butter in saucepan over medium-low; add flour and stir until smooth and bubbly. Add milk, salt, Worcestershire sauce, cheddar cheese, and 1/4 cup Parmesan cheese. Continue to cook, stirring constantly, until thick and bubbly.
Cut toast in half diagonally and place on a baking sheet (or use individual baking dishes). Arrange turkey slices on the toast and cover with hot cheese sauce. Top with tomato slices and bacon strips then sprinkle 1/2 cup Parmesan cheese over each sandwich. Place under broiler until hot and bubbly and lightly browned.
Hot brown sandwich serves 4.
