Cook the pasta in boiling salted water for eight to ten minutes, rinse with cold water and toss in two tablespoons of oil. Wash and clean the zucchini, cut in half lengthwise and diagonally into slices.
Wash parsley, dab dry and chop. Mix vinegar, mustard, parsley, three tablespoons of water and remaining oil and season with salt and pepper. Marinate the zucchini and pasta for 20 minutes in half the salad dressing.
Clean, wash and drain the salads and pluck them into bite-sized pieces. Fold the salad pieces into the marinated ingredients and garnish with thyme. The rest of the salad dressing is extra.
