Cook the pasta according to package directions, drain, and cool under cold running water. Set aside.
In your large mixing bowl, toss together the cooked pasta, frozen corn (no need to thaw it all the way), shredded chicken, red onion, and cilantro.
For the dressing, grab a smaller bowl and mix the cotija cheese, Greek yogurt, avocado oil mayo, sour cream, and lime juice. Stir it up until it's smooth and creamy.
Pour your dressing over the big bowl of pasta and veggies. Toss it gently but thoroughly so every bite’s coated in that tasty sauce.
Time to chill. Cover your salad and pop it in the fridge for at least 30 minutes. This waiting lets the flavors really get to know each other and blend so well.
When you’re ready to serve, give it a quick toss again. Taste and add more salt if you want.
Serve it cold or room temp. Enjoy all those fresh, creamy, spiced flavors that make this salad a standout.
