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 with cold
water and drain.
In a large bowl, whisk together the mayonnaise,
vinegar, lemon juice, artificial sweetener, garlic powder, dill, basil and
oregano, adjusting seasonings to suit your taste.
Add the pasta to the dressing and toss to coat.
Add the crab, green pepper, onion, olives, radishes, tomato and celery and
gently fold into the salad mixture. Cover and refrigerate until serving.
