Start by cooking your corn and pasta. Bring a pot of salted water to a boil and once boiling, add pasta and cook until al dente (about 9 minutes) then rinse with cool water to stop the cooking process and set aside.
If grilling corn, preheat a grill (or grill pan) to medium-high heat. Brush the corn with olive oil and grill for 2 minutes per side, or until charred to liking. Then remove from the grill and set aside. If using frozen corn, make sure corn is defrosted and cooled.
In a large bowl, combine the sour cream, mayo, lime juice, butter, garlic, cumin, chili powder and salt. Add the pasta, corn, cheese, green onion and cilantro and toss to evenly coat.
Taste and add more lime juice, salt or mayo to taste. Serve immediately or let chill until ready to serve (the flavors come together the longer it sits!).
When ready to serve, give pasta salad a good stir then sprinkle chili lime seasoning over top and enjoy!
