Preheat your Pit Boss Grill to 350˚F. Grill the corn cobs until slightly charred on all sides, about 10 minutes. Remove from the grill and allow to cool.
Remove the kernels of corn from the cob and set aside. In a separate bowl, mix together the sour cream, mayonnaise, lime juice, Champion Chicken seasoning, smoked paprika, and cilantro until smooth. Mix with the corn and feta cheese, then serve immediately.
