ingredients
EGG SALAD SANDWICH:
12 eggs
1 cup Chive Mayonnaise (recipe below)
1/4 cup parsley (finely chopped)
8 slices pumpernickel bread
Kosher salt and freshly ground black pepper (to taste)
CHIVE MAYONNAISE:

2 tablespoons warm water
2 teaspoons lemon juice
1 tablespoon distilled white vinegar
1/2 teaspoon Dijon mustard
1 teaspoon Kosher salt
1 and 1/2 cups vegetable oil
1/2 cup chives (roughly chopped)

directions
Place the eggs in a large saucepan and add enough water to cover them by at least 1 inch. Add 1 tablespoon of salt, then bring the water to a boil. Cover and remove from heat. Let stand, covered, for 10 minutes. Transfer eggs to prepared ice bath and allow to cool before peeling. Transfer peeled eggs to a cutting board and chop eggs into 1/2-inch pieces. Transfer chopped eggs to a large bowl, stir in the chive mayonnaise, parsley, and season with salt and pepper to taste.
For the Chive Mayonnaise: In the bowl of a food processor fitted with a blade attachment, add egg yolks, water, lemon juice, white vinegar, Dijon mustard,and salt and blend until smooth. With the motor running, slowly pour the vegetable oil into the food processor and blend until emulsified. Add chives and pulse until chives are finely chopped and well incorporated.
To serve, scoop desired amount of egg salad onto 4 slices of pumpernickel and top with the remaining 4 slices. Stack 2 sandwiches on top of each other, skewer both sides of the stacked sandwiches and slice in half on the diagonal. Serve!
