Creating this delightful Street Corn Creamy Cucumber Salad is straightforward. Follow these simple steps:

1. Prepare the Corn: If using fresh corn, cook it by boiling or grilling until tender. Let it cool, then cut the kernels off the cob. If using canned corn, simply drain it and rinse.

2. Chop the Vegetables: Dice the cucumber and avocado into small cubes. Finely chop the red onion and cilantro.

3. Make the Dressing: In a small bowl, mix together Greek yogurt (or sour cream), lime juice, chili powder, salt, and pepper. Stir until smooth and well-combined.

4. Combine Ingredients: In a large salad bowl, combine the sweet corn, diced cucumber, avocado, red onion, and cilantro.

5. Add the Dressing: Pour the creamy dressing over the corn and vegetable mixture. Toss gently until everything is well-coated in the dressing.

6. Chill (Optional): Let the salad chill in the refrigerator for 30 minutes if desired. This helps flavors meld and enhances the overall taste.

7. Serve: Stir the salad again before serving to ensure all ingredients are mixed well.
