Cook pasta according to package directions. Drain and rinse with cold water.

If using fresh corn, grill or pan-sear until slightly charred. If using frozen corn, thaw.

In a large bowl, combine cooked pasta, corn, red bell pepper, and red onion.

In a small bowl, whisk together mayonnaise, sour cream, lime juice, chili powder, garlic powder, salt, and pepper.

Pour dressing over pasta mixture and toss to combine.

Gently fold in cilantro and cotija cheese.

Serve chilled.
