Preheat grill on high for about 15 minutes.
Meanwhile, prep the corn. Cut the ends off of corn husks, removing extra pieces of husk that will be at risk for catching fire. If you like char on the kernels, then remove some of the husk completely.
When grill is preheated, turn the heat down a bit to a medium-high, and place the corn directly on the grill. Cover and cook 15-20 minutes, rotating about every 5 minutes with tongs.
When the corn is done, remove and place aside to cool for a bit.
Meanwhile, in a small bowl, make the dressing. Combine and mix Greek yogurt, Avocado oil, lime juice, cumin, ground red pepper, chili powder, and about 1/4 teaspoon both salt and pepper.
In a large bowl, combine the halved cherry tomatoes, diced red onion, diced avocado, crumbled Queso Fresco, and chopped cilantro.
When the corn is cooled enough to handle, remove the husks and carefully cut the kernels off of the ear. I do this by placing the corn vertically on the cutting board and cutting downward against the cob. Add the corn kernels to the large bowl.
Add the small bowl of dressing into the large salad bowl. Stir gently to combine. Taste and add more salt and pepper to your liking. Enjoy!
