Making the Creamy Street Corn Pasta Salad is straightforward if you follow these easy steps:

1. Cook the Pasta: In a large pot of boiling salted water, cook the pasta according to package instructions until al dente. Drain and rinse under cold water to stop the cooking process. Set aside.
2. Prepare the Corn: If using fresh corn, roast it in a skillet over medium heat until it starts to brown, around 5-6 minutes. If using frozen corn, simply thaw it.
3. Combine Vegetables: In a large mixing bowl, combine the corn, red bell pepper, and chopped cilantro.
4. Make the Dressing: In a separate small bowl, mix the sour cream, mayonnaise, lime juice, chili powder, garlic powder, salt, and pepper. Stir until smooth.
5. Combine Ingredients: Add the cooked pasta and the dressing to the corn and vegetables. Toss gently until everything is coated evenly.
6. Add Feta: Finally, fold in the crumbled feta cheese, being careful not to break it up too much.
7. Chill: Let the salad chill in the refrigerator for about 5 minutes to allow the flavors to meld together.
