Boil the eggs for 9-11 minutes depending on how hard boiled you prefer them.
When the eggs are ready preheat a nonstick pan over medium heat with some olive oil.
Fry the bread for 2-3 minutes on each side, until golden brown and crunchy.
Meanwhile peel the shrimps and set aside.
Combine the ingredients for the dressing in a bowl (saving one tablespoon of the chives for later).
Peel the eggs and cut in two.
When the bread is ready arrange the toast by putting lettuce at the bottom, followed by the sliced radishes.
Divide the shrimps between the two toast, top with dressing, fish roe, egg and sprinkle more chives on top.
Serve while the bread is warm.
