Clean and wash radishes. Cut off 2 slices, halve them and put them aside for garnishing. Cut remaining radishes into fine strips. Wash the herbs and dab dry. Pluck parsley leaves from the stalks, put some aside for garnishing.
Finely chop the remaining parsley. Cut chives into fine rolls. Mix quark and yoghurt. Fold in herbs, up to about 1 teaspoon, and season with salt, pepper and 1 pinch of sugar. Wash the peppers and cut out the core so that the stalk remains.
Cut the underside somewhat straight. Dice the pepper segments. Clean and wash the cucumber and cut it into fine slices. Place the cucumber slices close together on a plate. Sprinkle with paprika cubes.
Fill the quark into the peppers. Garnish with radish slices, chopped herbs and parsley leaves.
