Begin by cooking the fusilli pasta according to the package instructions until al dente. Drain and rinse under cold water to stop the cooking process. Set aside.
In a large bowl, combine the halved cherry tomatoes, diced cucumber, diced bell pepper, and finely chopped red onion.
Add the pitted and halved Kalamata olives and crumbled feta cheese to the bowl, mixing gently to incorporate.
In a smaller bowl, whisk together the olive oil, red wine vinegar, dried oregano, salt, and pepper until well combined.
Pour the dressing over the pasta and vegetable mixture. Add the cooked pasta and fresh parsley, then toss everything together until evenly coated.
Cover and refrigerate for at least 30 minutes to allow the flavors to meld.
Notes
Serve chilled and garnish with extra parsley and feta.
