Cook the pasta based on the package instructions to al dente. Drain and rinse with cool water. Then place in a large mixing bowl.
Gently stir in the celery, bell pepper, onion and shrimp. Set aside.
In a separate bowl, whisk together the dressing ingredients until well combined.
Pour the dressing over the pasta salad ingredients and stir until all the ingredients are well coated with the dressing.
Cover and refrigerate for at least 1 hour and then serve cold.
