01 - Bring a large pot of salted water to a boil. Cook rotini or penne according to package directions until al dente. Drain and rinse under cold water to halt cooking; set aside.
02 - Heat a large dry skillet over medium-high heat. Add corn kernels and sauté without oil for 3 to 5 minutes, tossing occasionally, until lightly charred and smoky. Remove from heat and let cool.
03 - In a large mixing bowl, combine the cooked chicken, halved cherry tomatoes, diced red onion, charred corn, jalapeño, and chopped cilantro. Toss gently to distribute evenly.
04 - In a separate bowl, whisk together mayonnaise, sour cream, lime juice, smoked paprika, chili powder, garlic powder, salt, black pepper, and crumbled Cotija cheese until smooth and well blended.
05 - Add the cooled pasta to the chicken and vegetable mixture. Pour the dressing over the top and toss thoroughly until every component is evenly coated.
06 - Just before serving, sprinkle crushed tortilla chips over the salad for a crispy finish. Garnish with additional Cotija cheese, fresh cilantro, and an extra squeeze of lime if desired.
07 - Serve chilled or at room temperature for the best flavor and texture.
