Add the feta, honey, garlic, and pistachios to a food processor. Blend until the cheese has a smooth and velvet-like consistency. You may need to scrape the feta off the sides of the food processor mid-blend with a spatula to be sure everything gets blended well.
Transfer the whipped feta onto a small plate or to a shallow bowl. To garnish the dip, drizzle a bit of honey and sprinkle some pistachios on top. Enjoy!
