Wash the pointed peppers, quarter them, remove the seeds and cut into very thin slices. Clean and quarter the fennel, cut out the stalk and cut into wafer-thin slices. Be sure to keep the fennel green.
Mix the paprika and fennel, make a marinade from salt, pepper, sugar, vinegar and oil. Mix with the salad ingredients and let it steep. Before serving, mix with the sour cream and sprinkle with the fennel greens.
