In a small bowl, combine your creamy dressing ingredients and whisk until smooth.

Thinly slice the onion and soak it in cold water for about 10 minutes.

Cook pasta in salted boiling water for 8-10 minutes until al dente, then drain and rinse.

In a large mixing bowl, combine the cooled pasta, drained onions, chopped cucumbers, and optional add-ins.

Pour the prepared dressing over the salad and toss gently to coat.

Chill the salad in the refrigerator for at least 40 minutes before serving.
