Place shredded cabbage in a large bowl with the olive oil, salt and lemon juice. Massage the cabbage for about a minute until it has shrunk in volume and is nicely tender. Fold in the sprouts and cilantro.
To make dressing, place all ingredients in a blender and blend on high until completely smooth and creamy. Add water to thin, if necessary. Season to taste. Store leftovers in a tightly sealed glass container in the fridge for up to five days.
