A great side dish for BBQ's or a picnic. I serve this a lot during the summer. It's a nice change from potato salad and not traditional macaroni salad. It's always a hit and the bowl is always empty before we leave :)
In a large mixing bowl add macaroni, crab, onions, celery adding mayonnaise a little at a time until you get your desired consistency. I don't care for mine too goopy. Mix well and add seasonings. Chill at least 2 hours before serving.
