Cook the Pasta: Fill a large pot with water, add salt, and bring it to a boil. Cook the pasta until it's firm to the bite, following the package instructions. Once done, drain the pasta and rinse it with cold water to stop the cooking process. Set it aside.

Prepare the Vegetables: While the pasta cooks, chop the broccoli, cucumber, red pepper, and green onion. Slice the black olives.

Make the Dressing: In a small bowl, whisk together the mayonnaise, white wine vinegar, kosher salt, black pepper, and sugar. Adjust seasoning to taste.

Assemble the Salad: Toss the chilled pasta into the bowl with the vegetables. Pour the dressing over the pasta and vegetables. Toss gently until everything is evenly coated.

Chill and Serve: Cover the salad and let it chill in the refrigerator for a minimum of 30 minutes to let the flavors blend together. Serve cold, garnished with extra green onion or a sprinkle of black pepper if desired.
