Bring the water for the pasta to the boil, add salt, and cook the pasta according to the instructions on the packet (usually around 10 minutes).
Toast the 50 g (4 tbsp) pine nuts in a large pan without oil over medium heat until they start to brown. Place 2.5 tbsp of the toasted pine nuts in the salad bowl and 1.5 tbsp in the blender jug for the dressing.
Cut off the ends of the zucchinis, halve them lengthwise, halve them again if you like, and then cut them into half or quarter slices about 5 mm (0.2 inch) thick.
In the pan where you fried the pine nuts, fry the zucchinis briefly in 2 tbsp olive oil, stirring occasionally, until the zucchini slices are just beginning to brown (they should not be brown) so that the zucchinis are still crunchy but no longer raw. Add to the salad bowl.
Meanwhile, chop the cocktail tomatoes and olives (cut both in half) and add to the salad bowl.
Rinse the beans in a sieve, drain, and add to the salad bowl with the pine nuts, tomatoes, and olives.
For the dressing, blend all the ingredients (pine nuts, arugula, basil, olive oil, balsamic vinegar, garlic, salt, and pepper).
At the end of the cooking time, pour the pasta into a sieve, rinse with cold water, and place in a salad bowl.
Pour the dressing over the pasta salad, briefly rinse the blender jug with 1-2 tbsp water if necessary, and pour over the salad.
Mix everything well.
I prefer to eat the Mediterranean pasta salad with arugula dressing lukewarm, but it also tastes great cold and well done from the fridge.
