In a large mixing bowl, combine the drained sweet corn, halved cherry tomatoes, diced green bell pepper, and chopped red onion.

In a separate bowl, mix together the sour cream, mayonnaise, lime juice, chili powder, salt, and black pepper until smooth.

Pour the dressing over the salad mixture and stir until everything is well coated.

Gently fold in the crushed Fritos just before serving to maintain their crunch.
