01 - In a mixing bowl, combine the softened cream cheese, goat cheese, chopped chives, lemon zest, and black pepper. Stir with a spatula until the mixture is completely smooth and uniformly blended.
02 - Cover the bowl and refrigerate the cheese mixture for 10 minutes to allow it to firm up, making it easier to handle during shaping.
03 - While the cheese chills, finely chop the pistachios and, if using, mix them with the crushed gluten-free crackers. Spread the coating mixture evenly across a flat plate or shallow dish.
04 - Using clean hands or a small cookie scoop, portion the chilled cheese mixture into balls approximately 1 tablespoon each. Roll each portion between your palms to form a smooth, even sphere.
05 - Roll each cheese ball in the pistachio-cracker coating mixture, pressing gently to ensure the crust adheres evenly on all sides.
06 - Arrange the coated cheese bites on a serving platter. Serve immediately at room temperature or refrigerate until ready to serve.
