Begin by bringing a large pot of salted water to a boil. Add fresh corn kernels and cook for 5–7 minutes, or until tender but still crisp. Once done, carefully drain the corn and set it aside to cool completely.

In a spacious mixing bowl, combine the cooled corn, diced cucumber, halved cherry tomatoes, and chopped red onion. Ensure that all the vegetables are evenly mixed.

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

Pour the prepared dressing over the vegetable mix and gently toss them together until everything is well-coated.

Before serving, sprinkle crumbled feta cheese and chopped cilantro over the salad for added flavor and visual appeal.
