Ingredients

24 slices cocktail-size pumpernickel bread 

1/2 cup mayonnaise 

2 tablespoons ketchup 

2 tablespoons sweet pickle relish 

1 tablespoon Dijon mustard 

8 ounces thinly-sliced corned beef 

1 cup sauerkraut 

8 ounces sliced Swiss cheese, cut into 2-inch squares 

Preparation

Preheat oven to 375 degrees.

Place bread on baking sheet and toast in the oven until lightly browned, 6 to 8 minutes. Let cool 10 minutes.

In a small bowl, stir together mayonnaise, ketchup, relish, and mustard until well combined. Spread each slice of bread with a thin layer of the mayonnaise mixture. Divide the corned beef among the bread, and top each with 2 teaspoons sauerkraut, followed by cheese slices. Transfer to oven and bake until cheese is melted and sandwiches are hot, about 10 minutes; serve warm.
