Clean the fennel, wash it and put aside some tender greenery for garnishing. Chop the fennel into thin slices. Peel onions and slice into fine rings. Peel 2 oranges so that the white skin is also removed. Cut the fruits crosswise into thin slices
Coarsely chop the nuts and roast them without fat. Halve 1 orange, squeeze the juice. Mix with vinegar, salt and pepper. Whip oil into it.
Stir in nuts. Mix fennel, oranges, onions and marinade, let stand for about 30 minutes. Garnish salad with fennel green. Wholemeal baguette tastes good with it
