How to Make It
Using a biscuit cutter, cut the sandwich bread into circles. Arrange bread slices on a lightly greased baking sheet. Broil 6 inches from heat for 3 to 4 minutes.
Melt butter in a saucepan over low heat; add flour, and cook, whisking constantly, until smooth. Gradually whisk in milk; cook over medium heat, whisking constantly, until mixture is thickened and bubbly. Add Cheddar cheese, whisking until cheese melts. Stir in diced turkey, salt, and ground red pepper.
Top bread evenly with warm cheese-turkey mixture. Sprinkle evenly with Parmesan cheese and half of bacon.
Bake at 500° for 2 minutes or until Parmesan is melted. Top with tomato slices, and sprinkle evenly with remaining bacon.
