Cook the spiral noodles in lightly salted water until just al dente and cool immediately to stop the cooking process. Drain.
Cut the pickles, bell pepper and onion into fine cubes and halve the olives.
For the dressing, mix the salad cream with 1 tablespoon of cucumber stock and 2 tablespoons of milk. Stir in a little Maggi, vegetable stock (instant powder) and lemon juice concentrate and season well with freshly ground pepper. Finally add two squirts of lemon juice concentrate. Fold the dressing into the pasta. Chop the tuna and add it. Now put the vegetables in the salad bowl and fold in well. Chill the salad and let it steep for about 30 minutes.
