2-1/2 cups shredded Cheddar cheese
2 tablespoons prepared mustard
1 cup mayonnaise
1 pound sliced pumpernickel party bread
In a large skillet over medium-high cook the bacon until evenly browned. Drain, crumble and set aside. In a medium bowl combine the bacon, cheese, mustard and mayonnaise. Stir well. Arrange the party bread on a cookie sheet. Spoon the mixture evenly onto each slice of bread.
Preheat the oven to broil. Broil for 5 minutes or until cheese melts and they are hot and bubbly.
