Classic Egg Salad Sandwich

Instructions:

Prepare the eggs:
Hard boil eggs, cool them under cold water, peel, and chop roughly.
Mix the salad:
In a bowl, combine chopped eggs, mayonnaise, mustard (if using), celery, and green onion. Stir gently to mix.
Season:
Add salt and pepper to taste. Sprinkle paprika if you want a little extra color and flavor.
Assemble the sandwich:
Toast bread if you like. Place a lettuce leaf on one slice, spread the egg salad evenly, then top with another bread slice.
Serve:
Cut sandwich diagonally and enjoy!
