Cook the mussel noodles al dente and let them evaporate.
In the meantime, add the vinegar, oil, and the oil from a tuna can to a large bowl. Cut or press the garlic into small pieces and add. Add the torn tuna, the leek cut into rings, the thinly cut into rings and halved onions, corn, mushrooms and the steamed pasta. Boil the beans, let them cool and add them as well.
We don`t usually have anything canned, but with this pasta salad, the mushrooms in the jar taste strangely better than fresh ones. But freshness also goes very well.
