Gently place the eggs in a small pot of warm water (make sure the water covers the egg!) and bring to a boil for about 13 minutes.

Drain, and submerge into ice-cold water to stop the cooking process.

Peel the eggs and remove the yolk from one of them. Dice the remaining eggs or mash slightly with a fork.

Add mayonnaise, mustard, salt and pepper (to taste) to eggs. Mash with a fork until desired texture - I like mine slightly chunky.

On one slice of bread, spread about 1/3 of egg mixture.
-
Top with a leaf of lettuce, then a slice of tomato.

Continue until all filling is used up.
