Step 1

Cook pasta according to package directions until al dente. Drain and then rinse under cold water.

Step 2

While pasta is cooking, prepare the dressing. In a large bowl, combine mayonnaise, sour cream, taco seasoning, garlic powder, salt, and pepper. Mix well.

Step 3

Add drained pasta, tomatoes, corn, black beans, cheese, and cilantro. Stir well to combine. Add more salt, pepper, and/or cilantro if needed.

Step 4

Refrigerate for at least 2 hours before serving so that flavors can deepen and pasta chills.
