This is my macaroni salad answer to my husband's hatred of celery! The green olives add a nice color and great flavor. Even if you do not care for green olives (I don't), they really work well here. I don't like macaroni salad without them now! NOTE: Sometimes I also add halved grape tomatoes for something different. I've also taken to adding a small amount of celery seed and sometimes a splash of white vinegar.
