Step 1

Bring a large pot of salted water to a boil. Add pasta and cook until al dente, about 8 minutes or according to package instructions. Drain and rinse pasta under cold water to stop the cooking process and to cool the pasta down.

Step 2

In a large mixing bowl or serving, combine cooked pasta, red onion, bell pepper, carrot, celery, and pickle.

Step 3

In a small mixing bowl, stir together mayonnaise, sour cream, vinegar, sugar, mustard, garlic powder, salt and pepper. Add dressing to salad and toss to combine.

Step 4

Serve immediately, or cover the bowl tightly with plastic cling wrap and refrigerator for at least 2 hours (or overnight for the best results). This will allow the flavors to really infuse into each other.
