How to eat pickled herring

I bought a jar of Swedish pickled herrings out of curiousity recently. Unlike the tangy flavour of pickled cucumbers, pickled herrings are incredibly salty. The texture is like sushi since the herrings aren't cooked.

Apart from seeing Detective Moser from Inspector Rex eat them out of the jar, I wasn't sure how to prepare them. This is what a German friend suggested:

We eat them for lunch together with cooked and buttered potatoes. Or you can make a salad (herring filets, onion, gherkins, apple, pork sausage, boiled eggs). Often people eat it as salad on brown bread (no pumpernickel!). Here´s a recipe for 1 person:

4 spoons plain yoghurt
a.. 1 small gherkin
b.. salt, pepper
c.. 75 g pickled herring
d.. 1 apple
e.. 100 g green salad
f.. 1 small red onion
g.. 100 g beetroot
h.. 2 branches dill
i.. 40 g whole-grain bread
