This is a take on the Prosperity Sandwich created in St. Louis in the 1920s, using holiday leftovers.
It is an open-faced sandwich made from toasted white bread topped with sliced turkey and ham or bacon, and a rich, cheesy white sauce, finished under the broiler. Use thick cut rustic bread to ensure it doesn’t get too soggy.

Servings 4 servings
Ingredients
- 5 tbsp. unsalted butter
- 1 cup mushrooms trimmed and sliced thin
- 1 medium shallot minced
- ½ tsp. salt
- ¼ cup all purpose flour
- 2 cups whole milk
- 2 cups sharp cheddar cheese shredded
- 2 tsp. Dijon mustard
- 2 tsp. Worcestershire sauce
- ½ tsp. pepper
- 4 slices rustic white bread 3/4-inch-thick slices
- 8 slices roast turkey sliced thin
- 8 slices ham slices thin
- 2 large tomatoes cored, cut into 8 (1/4-inch-thick) slices, and patted dry
Instructions
- Melt 1 tablespoon butter in large saucepan over medium-high heat. Add mushrooms, shallot, and salt and cook, stirring occasionally, until well browned, 5 to 7 minutes. Transfer to bowl.
- Melt remaining 4 tablespoons butter in now-empty saucepan over medium heat. Stir in flour and cook for 1 minute. Slowly whisk in milk and bring to simmer. Reduce heat to low and cook, stirring occasionally, until thickened, 4 to 6 minutes. Off heat, stir in 1/2 cup cheddar, mustard, Worcestershire, and pepper; set aside.
- Adjust oven rack 5 inches from broiler element and heat broiler. Line rimmed baking sheet with aluminum foil and spray with vegetable oil spray. Arrange bread slices on prepared baking sheet and broil until toasted, 1 to 2 minutes per side.
- Divide mushroom mixture among toasted bread slices. Arrange 2 slices turkey, 2 slices ham, and 2 slices tomato over mushrooms on each slice of toast. Spoon 1/2 cup cheese sauce evenly over each sandwich and sprinkle with remaining 1 1/2 cups cheddar. Broil until cheddar is browned, 3 to 5 minutes. Let cool for 5 minutes. Serve.
