In a mixing bowl, combine softened cream cheese, shredded cheddar, and crumbled blue cheese.
Add chopped chives, red bell pepper, garlic powder, salt, and pepper. Mix well to combine all ingredients evenly.
Cover the bowl with plastic wrap and refrigerate for at least 30 minutes to allow flavors to meld.
Once chilled, scoop out small amounts of the cheese mixture and roll them into bite-sized balls.
Roll each ball in chopped nuts, ensuring they are fully coated.
Place the cheese ball bites on a serving platter and chill until ready to serve.
