Step 1

Heat a large cast-iron or stainless steel skillet over medium-high heat. Add the oil, then corn kernels, poblano, green onion whites, salt, and pepper. Cook until the corn begins to char, 8 to 10 minutes. Stir in the garlic. Remove from heat and transfer the mixture to a large bowl.

Step 2

Add the cheese, cilantro, mayonnaise, sour cream, lime zest, lime juice, chili powder, and the green onion greens. Fold to combine. Season with salt, pepper, and chili powder to taste.
