Steam or boil cauliflower for 8-10 minutes. While cauliflower is steaming, in another pan, add oil and sauté onion and garlic until soft– (if you spray the pan with herb infused Avocado oil, there will be even more flavor).
Place cauliflower, sautéed onion and garlic, and fresh herbs and seasonings in a VitaMix or other high-speed blender. Add butter alternative and blend until smooth. Make sure when placing cauliflower and sautéed onion and garlic in the blender– do not pour in any residual water/oil from cooking or it will be quite soupy.
Taste and add sea salt and pepper if needed.
