Using a food processor, shred the cabbage and rice the cauliflower. If using frozen riced cauliflower, defrost 1 cup. Heat coconut oil in large saute pan. Add onion plus 1/4 tsp salt and cook until onion softens, about 3 minutes. Add shredded cabbage (you might have to do this in batches). Once all the cabbage is in the saute pan, stir in ginger, spices and remaining salt.Then add peas and cauliflower and mix gently to combine. Top with lemon before serving.
