Add the mayonnaise, sour cream, garlic, Cajun seasoning, scallions and roasted red pepper. Mix well and season to taste with salt and pepper. Cover and refrigerate for at least 2 hours to allow the flavors to blend.
Serve with raw veggies like red and green bell pepper, carrots, celery, cucumber and zucchini.
