01 - In a mixing bowl, combine the cream cheese, goat cheese, chives, lemon zest, and black pepper. Stir until the mixture is smooth and uniformly blended.
02 - Refrigerate the cheese mixture for 10 minutes to firm up, making it easier to handle during rolling.
03 - Finely chop the pistachios and, if using, mix with crushed crackers. Spread the coating mixture evenly on a plate.
04 - Using clean hands, roll the chilled cheese mixture into small balls, approximately 1 tablespoon each.
05 - Roll each cheese ball in the pistachio coating, pressing gently so the nuts adhere evenly to the surface.
06 - Arrange the coated cheese bites on a serving platter. Serve immediately or refrigerate until ready to serve.
