Begin by removing the leaves and stem from the head of cauliflower. Using a grater or food processor, grate the cauliflower until you have approximately 4 cups. The texture should resemble couscous.
Thinly slice the red cabbage and dino kale. Make sure the kale is finely sliced to make it easier to eat. Chop the green onions and set all the vegetables aside.
In a large mixing bowl, combine the grated cauliflower, red cabbage, kale, and green onions. Add the dried cranberries and chopped walnuts for a delightful crunch and sweetness.
In a small bowl, whisk together the olive oil, fresh lemon juice, and stone ground mustard. Season with salt and cracked pepper to taste. Adjust the dressing to your liking; if you prefer a tangier flavor, add more lemon juice.
Pour the dressing over the vegetable mixture and toss until everything is evenly coated. Make sure the flavors meld together beautifully.
Taste your Raw Cauliflower Couscous with Kale and Cabbage and adjust seasoning if necessary. Serve immediately or let it chill in the fridge for a bit to enhance the flavors.
