Boil the eggs: Start by placing your eggs in a pot and covering them with cold water. Bring to a boil, then reduce heat and simmer for 10-12 minutes until hard-boiled.

Cool the eggs: Once boiled, transfer the eggs to an ice bath or run them under cold water. Let them cool for about 5 minutes.

Peel the eggs: Gently tap each egg on a hard surface to crack the shell. Roll it lightly to loosen the shell, then peel under running water.

Chop the eggs: Using a sharp knife, chop the peeled eggs into small pieces.

Mix in ingredients: In a bowl, combine chopped eggs with mayonnaise, mustard, salt, and pepper. Stir gently until well coated.

Add flavor: Consider mixing in finely chopped celery or green onions for crunch and freshness. Adjust seasoning to taste.
