Cut the frozen salmon fillet into very small cubes, chop again with a sharp knife, mix in the chopped spring onions, add salt, pepper and lemon oil. (If there is no lemon oil, then very important: first mix olive oil into the finely chopped amount of salmon before adding acid or lemon or lime juice)
Then add the remaining ingredients.
(You can also add parsley, fresh basil or, depending on your taste, fresh coriander!)
Taste!
I like to serve potato pancakes (Baggers or Reiber-Datschi) or just baguettes.
