Step 1: Start by bringing a pot of water to a boil over high heat. Add the fresh corn kernels and cook them for 5–7 minutes until they are tender-crisp with a vibrant golden hue. Once done, drain the corn and let it cool completely before moving on to the next step.

Step 2: In a large mixing bowl, combine the cooled corn with diced cucumber, halved cherry tomatoes, and finely chopped red onion. Use a spatula to gently fold the ingredients together, ensuring an even distribution of colors and textures.

Step 3: In a separate bowl, whisk together mayonnaise, sour cream, lime juice, chili powder, salt, and pepper until the dressing is smooth and well-combined.

Step 4: Pour the dressing over the vegetable mixture in the large bowl. Using a gentle folding motion with a spatula, toss everything together until the vegetables are completely coated in the creamy dressing.

Step 5: Before serving, garnish your salad with crumbled feta cheese and chopped cilantro. Optionally, add diced jalapeños for extra spice.
