Boil the bowtie pasta according to the package instructions. Drain and let it cool.
In a large mixing bowl, combine the cooked and cooled pasta with cherry tomatoes, cucumber, red onion, black olives, feta cheese, and fresh basil.
In a separate small bowl, whisk together the dressing ingredients (see below).
Pour the dressing over the pasta mixture and toss gently to coat evenly.
Refrigerate to allow the flavors to meld together for at least 30 minutes.
