01 - Bring a large pot of salted water to a rolling boil. Cook rotini or penne according to package directions until al dente. Drain thoroughly and rinse under cold running water to halt cooking. Set aside and allow to cool completely.
02 - Heat a dry skillet over medium-high heat. Add corn kernels in an even layer and sauté without oil for 3 to 5 minutes, stirring occasionally, until lightly charred and caramelized. Remove from heat and let cool.
03 - In a large mixing bowl, toss together the diced chicken, halved cherry tomatoes, finely diced red onion, charred corn kernels, diced jalapeño, and chopped cilantro until evenly distributed.
04 - In a separate bowl, whisk together mayonnaise, sour cream, fresh 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 gently until every component is thoroughly and evenly coated.
06 - Just before serving, sprinkle crushed tortilla chips over the salad for a crunchy finish. Garnish with additional crumbled Cotija cheese, fresh cilantro leaves, and an extra squeeze of lime if desired. Serve chilled or at room temperature.
