Cook the pasta according to the package instructions, adding a generous pinch of salt to the water. When nearly done, add the broccoli florets and cook for about 30 seconds. Drain thoroughly and rinse with cold water to stop cooking.
In a large bowl, whisk together the mayonnaise, vinegar, salt, pepper, and sugar. Add the cooked pasta and broccoli to the dressing and toss to coat evenly.
Add the diced cucumber, red pepper, olives, and green onion. Mix well. Cover and refrigerate until ready to serve, stirring again before serving.
