Boil a pot of water and cook the pasta according to package instructions until al dente.

In a skillet over medium heat, add corn and cook until golden charred for about 5-7 minutes.

Once the pasta is cooked, drain and rinse under cold water.

In a large bowl, combine the cooked pasta, charred corn, cherry tomatoes, bell pepper, red onion, and cilantro.

In a separate small bowl, mix together the mayonnaise, sour cream, lime juice, chili powder, salt, and pepper to make the dressing.

Pour the dressing over the pasta and veggies, tossing to coat well, and sprinkle crumbled feta on top.
