Place the softened cream cheese, shredded pepper jack, 1 cup chopped pecans, 1 cup chopped dried cranberries, about 1 tablespoon of the chopped chives, salt, onion powder, and black pepper into the bowl of a stand mixer.
Fit the mixer with the paddle attachment and blend on medium speed until the cheese mixture becomes smooth, creamy, and evenly combined.
Stop the mixer once or twice during blending to scrape the sides and bottom of the bowl, ensuring that all ingredients are thoroughly incorporated.
Measure the prepared cheese mixture into 1-tablespoon portions. Using clean hands, gently roll each portion into a compact ball.
Arrange the shaped cheese balls on a baking sheet covered with wax paper, continuing until all of the cheese mixture has been portioned.
Transfer the tray to the refrigerator and chill the cheese balls for a minimum of 2 hours. This firming period allows them to retain their shape more effectively during coating.
In a small bowl, stir together 1 cup chopped pecans, 1 cup chopped dried cranberries, and about 1 tablespoon of the remaining chopped chives.
Combine thoroughly so the pecans, cranberries, and chives are distributed evenly throughout the coating mixture.
Remove the chilled cheese balls from the refrigerator.
Roll each ball through the prepared cranberry-pecan mixture, gently pressing the coating onto every side until the surface is completely covered.
Insert one pretzel stick into the center of each coated cheese ball to create an individual, easy-to-serve appetizer.
Place the completed bites back in the refrigerator and keep them chilled until serving.
