1-First Step: Bring a large pot of salted water to a boil. Add the spaghetti and cook according to package instructions, usually 8-10 minutes, until al dente. Once cooked, drain and rinse under cold water to stop cooking and cool the pasta.

2-Second Step: While the pasta cooks, prepare the vegetables by halving cherry tomatoes, slicing black olives, dicing cucumber, finely chopping red onion, and chopping fresh basil. For dietary adjustments, consider substituting any vegetables or adding preferred seasonal options.

3-Third Step: In a large mixing bowl, combine the cooled spaghetti with the prepared vegetables. Toss gently to distribute ingredients evenly.

4-Fourth Step: In a small bowl, whisk together the extra virgin olive oil, red wine vinegar, salt, and pepper to create the dressing. Adjust ingredient amounts for low-calorie or different flavor preferences.

5-Fifth Step: Pour the dressing over the pasta and vegetable mixture. Toss thoroughly to coat all ingredients.

6-Sixth Step: Add crumbled feta cheese (or vegan substitute) and gently mix to incorporate.

7-Final Step: Refrigerate the salad for at least 30 minutes to allow flavors to meld. Before serving, taste and adjust seasoning as needed. This salad can be served chilled or at room temperature, making it adaptable for different occasions and preferences.
