Beetroot salad

2 -4 Beetroots, boiled
1 onion (depends how much raw onion you like in a salad)
1 green sour apple
about 2dl sour cream (rømme, kermaviili, yoghourt or rømmekolle are all fine)
pinch of salt, pinch of sugar

Chop the vegetables into small pieces. Add sour cream and spices. Yes, it is possible to add other spices as well but it is actually very good without.
