Place the eggs in cold water and set on a high heat until boiling.
As soon as they start boiling, set the timer for 7 mins.
Meanwhile, finely chop the onion & dill.
Once the eggs have boiled, either place into an ice bath or drain the water and fill back up with cold water and allow the eggs to sit for a few minutes.
Carefully peel the shell and place the eggs into a medium sized, wide bowl.
Roughly mash with a fork and add in the onion, dill, mustard, mayo and seasoning.
Mix until thoroughly combined.
Top the mixture on either toasted or fresh bread and finish with some slices of fresh cucumber.
