01 - Bring a large pot of salted water to a rolling boil. Cook bow tie pasta according to package directions until al dente. Drain in a strainer and rinse thoroughly 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.
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 creamy.
04 - Pour the prepared dressing over the pasta and vegetable mixture. Toss gently but thoroughly until every component is evenly coated.
05 - Gently fold in the crumbled feta cheese, if using, taking care not to break it down too much.
06 - Cover and refrigerate for at least 30 minutes so the dressing penetrates the pasta and the flavors meld together.
07 - Give the salad one final toss before serving. Taste and adjust the salt and pepper as needed.
