Follow these straightforward steps to prepare your delicious Healthy Street Corn Pasta Salad:

1. Cook the Pasta: Bring a large pot of salted water to a boil. Add the whole wheat pasta and cook according to the package instructions until al dente. Drain and set aside to cool.

2. Prepare the Grilled Corn: If using fresh corn, grill the corn cobs until lightly charred. Cut the kernels off the cob and place them in a large mixing bowl. If using frozen corn, cook it according to package instructions, then add it directly to the bowl.

3. Add Vegetables: To the bowl of corn, add the diced red bell pepper, chopped red onion, halved cherry tomatoes, and diced avocado.

4. Make the Dressing: In a separate small bowl, whisk together the Greek yogurt, mayonnaise, lime juice, chili powder, salt, and pepper until smooth and well combined.

5. Combine Ingredients: Once the pasta has cooled, add it to the bowl with the veggies and corn. Pour the dressing over the mixture and gently toss everything together until evenly coated.

6. Add Fresh Herbs: Lastly, fold in the chopped cilantro, mixing gently to avoid mashing the avocado.

7. Adjust Seasoning: Taste and adjust seasoning with more salt, pepper, or lime juice as desired.

8. Chill (Optional): For best flavor, cover the salad and refrigerate for at least 30 minutes before serving, allowing the flavors to meld.
