For the colorful pasta salad, cook the pasta in salted water until al dente according to the package instructions. Drain and keep some of the cooking water. Rinse with cold water and mix in a little olive oil to prevent the pasta from sticking together.
Meanwhile, wash the peppers, remove the stalk and seeds and cut into small cubes.
Peel the cucumbers, cut them in half lengthwise and scrape out the seeds with a small spoon. Peel onions and chop finely. Wash herbs, pat dry and pluck or chop. Mix vegetables, pasta and half of the herbs.
Mix vinegar with 4-6 tablespoons pasta cooking water, season with salt, a pinch of sugar and pepper. Mix in the oil.
Let the colorful pasta salad soak for a while, sprinkle with fresh herbs and serve.
