Cook pasta according to package instructions. Drain and allow to cool (if in a hurry you can run cold water over the pasta, drain well).
In a large serving bowl combine pasta, bell pepper, tomatoes, avocado, black beans, corn, scallions, arugula, and chicken.
For the dressing whisk together in a small bowl the Chipotle Aioli, sour cream, lime juice and salt and pepper.
Drizzle dressing over pasta salad ingredients and add the cilantro. Toss until all ingredients are lightly coated. Season to taste with salt and pepper. Serve immediately.
