01 - In a mixing bowl, combine the softened cream cheese, goat cheese, chives, lemon zest, and black pepper. Stir with a spatula until the mixture is smooth and uniformly blended.
02 - Cover the bowl and refrigerate the cheese mixture for 10 minutes to firm it up, making it easier to handle during rolling.
03 - While the cheese chills, finely chop the pistachios. If using crushed crackers, mix them into the pistachios. Spread the coating mixture evenly across a shallow plate or rimmed baking sheet.
04 - Using clean hands or a small cookie scoop, portion the cheese mixture into roughly 1 tablespoon-sized amounts. Roll each portion between your palms to form a smooth, round ball.
05 - Roll each cheese ball in the pistachio coating, pressing gently so the nuts adhere evenly to the entire surface.
06 - Place the coated cheese bites on a serving platter. Serve immediately at room temperature or refrigerate until ready to serve.
