Heat the grill to medium-high heat.
Prep the corn. Remove the husk and excess silk. Rub the ears of corn with oil, giving them a slight coating.
Grill your corn. Once the grill is hot, place the corn directly on the grill. Cook for about 10-15 minutes, rotating every few minutes until the corn is cooked and has some char marks. Let cool for a couple of minutes and then remove the corn kernels from the cob with a sharp knife.
While the corn cooks, make the sauce. In a medium-large bowl, mix the greek yogurt, mayo, lime juice, paprika, garlic powder, salt, and pepper.
Make salad. Add corn kernels, cotija cheese, jalapeno, cilantro, salt, and pepper to the bowl with your dressing. Stir well to combine. Adjust according to taste.
Enjoy! Garnish with more cheese and cilantro when serving.
