In a large bowl, combine the drained corn, mayonnaise, diced red onion, shredded cheddar cheese, and optional diced jalapeno peppers.
Season with salt and black pepper to taste. Mix gently until all ingredients are well combined.
Just before serving, add the Fritos corn chips to the salad and gently fold them in. Be careful not to crush them too much, as you want to retain some crunch.
Serve immediately and enjoy!
Notes
For best results, add the Fritos just before serving to prevent them from getting soggy. This salad is a crowd-pleaser and can be customized with other ingredients like diced bell peppers or cilantro.
