Wash the potatoes and do not cook them too soft, peel them, cut into fine slices and let them cool down.
Peel the cucumber, grate it roughly, season with salt, leave to stand a little and squeeze out. Mix the sour cream with the pressed garlic, dill, pepper and salt and mix with the cucumber.
Mix in the cooled potato slices and season to taste. Halve the cocktail tomatoes and spread them on the salad with the mashed feta.
When seasoning the salad, pay attention to how much the feta is salted. The light version made from cow`s milk, which I prefer, is not as salty and mild in taste.
Delicious as a side dish for grilling or as a small meal.
