Creating this amazing Pasta Salad is straightforward. Just follow these simple steps:

1. Cook the Pasta: In a large pot, bring salted water to a boil. Add the pasta and cook according to the package instructions until al dente. Drain and rinse under cold water to stop the cooking process.
2. Chop the Vegetables: While the pasta is cooking, chop the cherry tomatoes, cucumber, bell pepper, and red onion into bite-sized pieces.
3. Prepare the Dressing: In a small bowl, whisk together olive oil, red wine vinegar, dried oregano, salt, and pepper until well combined.
4. Combine Ingredients: In a large mixing bowl, add the cooked pasta, chopped vegetables, olives, and parsley. If using, add the crumbled feta cheese.
5. Dress the Salad: Pour the dressing over the pasta salad and toss until everything is evenly coated.
6. Chill: For the best flavor, cover and place the salad in the refrigerator for at least 15 minutes before serving.
7. Taste and Adjust: Before serving, taste the salad and adjust the seasoning if necessary. You can add more salt, pepper, or even a splash of vinegar to enhance the flavors.
