  • 30 ounces frozen cauliflower florets or 2 heads of cauliflower
  • ¼ cup whole milk or almond or soy milk.
  • 2 Tablespoons butter softened, more to taste
  • ½ teaspoon salt
  • ¼ teaspoon pepper

  • Place cauliflower in a large pot. Add milk, butter, salt, and pepper and puree with an immersion blender. Alternatively, pulse cooked cauliflower in a food processor until mashed to desired consistency.

  • Temporarily move cauliflower to a serving dish.
  • Heat olive oil over medium-high in the same large pot that is now empty.
  • Add green onion, garlic, and kale and sauté for about 5 minutes or until the onions are softened and the kale is wilted.
  • Return mashed cauliflower to the pot and stir to thoroughly combine.
  • Garnish with green onions. Salt and pepper to taste.
