Cheese: Wrap each grape in goat cheese, rolling between your palms to evenly coat the grape.
Nuts: Use a food processor to grind pistachios into coarse pieces. (You could also chop them up by hand). Transfer pistachios to a plate and roll each goat cheese covered grape in the nuts. Roll between your palms to press the pistachios in the cheese.
Serve: Serve immediately or store covered in the refrigerator until ready to serve. Optionally drizzle with honey or sprinkle with salt and pepper just before serving.
