1 dozen hard-boiled large eggs, peeled and chopped finely
3/4 cup mayonnaise
Juice of 1/2 lemon
1 teaspoon Dijon mustard
For assembling:
10 slices bread (like white bread or Brioche)
Directions
Combine all the egg salad ingredients in a large mixing bowl and stir. Chill for 1 hour.
To assemble, lay bread on a cutting board and place 1/2 cup egg salad on a slice of bread. Press and shape into a rectangle, inside of the crusts, for even distribution. Top with bread. Press down firmly to set. Using a serrated edge knife, slice off the crusts.
