The pasta would absorb the dressing so rinsing won't get rid of the flavor so I would do something that doesn't cover it, but work with it. I would remove the broc, but keep the olives. Rinse any extra dressing and set pasta with olives aside.
Brown up some spicy italian sausage, add some olive oil and small can of tomato paste. Add the pasta and olives and cook until warmed through, then add fresh or frozen spinach, cook until it wilts.
