For ease of use I love buying the bags of pre-shredded cabbage and carrots (labeled as coleslaw mix) in my produce section. If you prefer to shred your own cabbage and carrots then you will need about 6 cups total. It can be red cabbage, green cabbage, or a mixture of the two. You can also use a shredded kale or broccoli slaw blend as a substitute for the cabbage coleslaw blend.
