Steam the corn per the package directions in the microwave. Cool slightly.
While the corn cools dice the poblano pepper, red pepper and red onion.
In a large bowl whisk together the mayonnaise, sour cream, seasoned salt, lemon pepper, granulated garlic, paprika, onion powder and cumin until fully combined.
To the bowl add corn, poblano pepper, red pepper, red onion and shredded cheddar cheese. Mix to evenly distribute, then cover and chill at least 2 hours.
Just before serving roughly crush the fritos and mix into the salad. (The fritos shouldn't be finely crushed, large whole pieces work!)
Serve immediately with Fritos Scoops for dipping or as a side dish salad.
