Bring a large pot of salted water to a boil. Add the cauliflower florets and cook for 5-6 minutes, just until fork tender but not mush...yet.
Drain well, then add it to a food processor or high-speed blender with a large slotted spoon.
Add in the garlic, ghee, parmesan cheese, sea salt, and pepper.
Add the milk one Tablespoon by Tablespoon while pureeing until you find the consistency you like.
Puree until smooth, and to your desired consistency.
Add the mashed cauliflower to a serving dish or bowl and garnish with chives.
Serve warm and enjoy!
