Hard-boil the eggs by placing them in a pot of water, bringing it to a boil, then covering and letting sit for 10-12 minutes. Cool in ice water and peel.

In a mixing bowl, chop the hard-boiled eggs into small pieces using a fork.

Add mayonnaise, mustard, celery, red onion, salt, pepper, and dill. Mix well until combined.

Serve immediately on bread, in a wrap, or over a bed of greens.
