Cook the pasta in salted water according to the package instructions until it's al dente. Drain in a colander, then rinse under cold water to stop the cooking process and cool the pasta. Drain well, and set it aside.
Make the dressing - Combine all dressing ingredients in the order they are listed in a large measuring cup and whisk to combine (or shake it up in a lidded mason jar).
Combine the salad ingredients in a large bowl: pasta, cucumbers, tomato, bell pepper, red onion, feta cheese, kalamata olives and parsley. If the dressing has separated, give it a good shake before drizzling it over the salad. Add a spoonful of juice from Kalamata olives if desired and toss the salad to combine.
Refrigerate for at least 30 minutes for the flavors to meld, or up to 24 hours. Since the pasta will absorb some of the dressing, taste the salad after refrigeration and adjust the seasoning as needed.
