Preparation

• Cook the eggs: Tap one end of each egg on a surface to create a small crack. Place the eggs in a pot, cover with water, bring to a boil, then turn off the heat, cover, and let sit for 10 minutes.
• Transfer the cooked eggs to a bowl of cold water and peel them. Rinse the eggs to remove any shell residues.
• Separate the egg whites from the yolks. Place the yolks in a bowl and mash them with a fork.
• Chop the egg whites into approximately 5mm cubes.
• Gently mix the egg whites, yolks, and 40g of mayonnaise. Season with salt and pepper.
• Prepare 4 slices of bread. If desired, lightly butter the slices and add a thin layer of mustard. Place a portion of the egg mixture on 2 slices, with a thicker layer in the middle. Top with the remaining slices of bread.
• Trim the crusts (if not using 100% mie bread) and cut each sandwich in half or quarters for serving.
