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 evenly incorporated.
02 - Refrigerate the cheese mixture for 10 minutes to firm up, which will make it easier to handle and shape.
03 - While the cheese chills, finely chop the pistachios. If using crushed crackers for extra crunch, mix them into the chopped pistachios. Spread the coating mixture evenly across a flat plate.
04 - Using clean hands, scoop approximately 1 tablespoon of the chilled cheese mixture and roll it into a smooth ball. Repeat until all the mixture has been shaped.
05 - Roll each cheese ball gently in the pistachio coating, pressing lightly so the nuts adhere evenly to the entire surface.
06 - Arrange the coated cheese bites on a serving platter. Serve immediately, or cover and refrigerate until ready to serve.
