Shredding cabbage can be tricky, however I have some top tips to make this a very quick process! Use a sharp knife: Remove the center core from the cabbage and cut with a sharp knife. This is the most time consuming option. Use a food processor: Cut the core from the cabbage and cut it into pieces small enough to fit in the top of your food processor. Add the shredding blade (not grater) to the food processor and turn on the food processor. Feed the cabbage through the feeder tube at the top of the food processor and it will shred all the cabbage in about 1 minute or less. Use a  spiralizer: Place the cabbage on the spiralizer so the core is in the pointy spikes and the top of the cabbage is by the blade. Making sure you have a flat blade (on the Insprializer it will be Blade D), spiralize the cabbage. This tends to get a little messy but works really well.  Takes about 1-2 minutes. Use a mandolin: Mandolins are a great way to quickly shred up cabbage or cut vegetables into even slices. However, these are very sharp and can be very dangerous. I cut my hand with one and do not recommend you using them without proper gloves to help shield your hands from the blade. Go slow.
