Begin by boiling the fusilli pasta in salted water until it reaches a perfect al dente texture. Once cooked, drain the pasta and rinse it under cold water to halt the cooking process.
In a spacious bowl, mix the cooled fusilli with grape tomatoes, bell pepper, Kalamata olives, feta cheese, green onions, and parsley, ensuring everything is evenly distributed.
Drizzle the balsamic vinaigrette over the mixture and gently fold everything together, allowing the dressing to coat the ingredients. Adjust the seasoning with salt and pepper as desired.
Let the pasta salad sit for about 30 minutes in the refrigerator, giving the flavors time to blend beautifully.
Serve the salad cold or at room temperature for a refreshing dish.
