01 - Bring a large pot of salted water to a rolling boil. Cook bow tie pasta according to package directions until al dente. Drain well and rinse under cold running water to halt cooking and cool the pasta completely.
02 - In a large mixing bowl, toss together the cooled pasta, halved cherry tomatoes, diced cucumber, diced red bell pepper, thinly sliced red onion, sliced black olives, and chopped fresh parsley until evenly distributed.
03 - In a small bowl or mason jar, whisk together the extra-virgin olive oil, red wine vinegar, minced garlic, dried oregano, Dijon mustard, salt, and black pepper until the mixture is fully emulsified and smooth.
04 - Pour the prepared dressing over the pasta and vegetable mixture. Toss thoroughly, ensuring every component is evenly coated with the vinaigrette.
05 - Gently fold in the crumbled feta cheese, if using, taking care not to break it down too much during mixing.
06 - Cover and refrigerate for at least 30 minutes to allow the flavors to meld and develop.
07 - Give the salad one final toss before serving. Taste and adjust seasoning with additional salt or pepper as needed.
