Step 1: Bring a large pot of water to a boil and add fresh corn kernels. Cook for 5–7 minutes until the corn is tender yet crisp; carefully drain and let it cool completely.

Step 2: In a large mixing bowl, combine the cooled corn, diced cucumber, halved cherry tomatoes, and chopped red onion. Stir gently with a spatula.

Step 3: In a separate bowl, whisk together mayonnaise, sour cream, lime juice, chili powder, salt, and pepper until smooth.

Step 4: Pour the creamy dressing over the vegetable mixture and gently toss everything together until well-coated.

Step 5: Sprinkle crumbled feta cheese and fresh cilantro over the top before serving chilled.
