Cook cabbage or kale and onions in broth over medium heat until tender.
Steam sweet potatoes until tender, then cut into cubes.
Add cabbage and onions mixture and sweet potatoes to blender or mixer and blend until you reach a "fluffy" consistency. Add spices and mix well. Reheat mixture if necessary.
Just before serving, stir in the flaxseed oil and garnish with chopped green onions.
