1. Peel the eggs and chop them into pieces.
2. Mix the eggs in a bowl with the mayonnaise, mustard, capers, caper juice, pepper, and a good sprinkle salt. If desired, add the sunflower seeds.
To serve, spread on toasted grainy bread, then garnish with additional salt, pepper, and some chopped chives. Or for a real treat, top with a few strips of crispy bacon.
