In a large mixing bowl, combine cream cheese, sour cream, and shredded cheddar cheese. Blend until smooth and creamy, about 2-3 minutes.

Incorporate bell peppers, corn, green onions, cilantro, and lime juice into the cheese mixture. Fold together gently.

Transfer the mixture onto plastic wrap and mold it into a log shape. Wrap tightly and refrigerate for at least 2 hours.

After chilling, remove the cheese log from the refrigerator and unwrap. Roll in chopped herbs or diced nuts if desired.

Allow the cheese log to rest at room temperature for about 30 minutes before serving with tortilla chips or fresh veggies.
