1 lb rotini or shell shaped pasta
3/4 cup mild barbecue sauce
1 cup mayonnaise
1/2 cup grated Parmesan cheese
1/4 cup red wine vinegar
3/4 lb cooked shrimp, peeled and develined
1 1/2 cup diced celery
1/2 cup diced onion
Chopped fresh parsley for garnish (optional)

In a large pot of boiling salted water, cook pasta just until tender.  Meanwhile,
in a medium sized bowl, combine the barbecue sauce, mayonnaise, cheese, and vinegar.
Drain the pasta, rinse under cold water and drain, and put into a large bowl.  Add the
shrimp, celery and onion and toss gently.  Add the barbecue sauce mixture and toss
again to mix.  Cover and refrigerate until chilled.  Garnish with chopped fresh
parsley, if desired.
