Bring a large pot of lightly salted water to a boil. Add pasta and cook for 8 to 10 minutes or until al dente; rinse under cold water until cool and drain.
While pasta is cooking, chop celery and crabmeat. Run hot water over peas to defrost.
In a large bowl, whisk together the mayonnaise, SPLENDA® Granulated Sweetener, vinegar, milk, salt and pepper. Add the pasta, celery and crabmeat and stir until evenly coated. Adjust the salt, SPLENDA® Granulated Sweetener or mayonnaise to suit your taste. Chill several hours before serving.
