Peel the cucumbers and grate them into thin slices. 

Salt them and let them stand for a bit.

 

Make thickener, add finely chopped onion, red paprika dust and drained cucumbers.

 

Saute cucumbers for a little, fill in with water and let boil.

 

Optionally, you can add at the end several potatoe cubes.
Before you serve, put on top some sour cream.
