You could use shredded broccoli or cauliflower stems instead of cabbage. You could also do this with brussels sprouts. If you don't want a slaw at all, use the dressing for romaine and/or kale.
Using the shredder attachments from your food processor, shred the cabbage and carrots. *Note: they use different attachments: the single blade is for the cabbage, and the shredder for the carrots.
If you don’t have a food processor, shred by hand on a cheese grater. If you don’t have a cheese grater, thinly slice the cabbage, and use a handheld grater for the carrots.
Place the veggies in a bowl.
Pour the remaining marinade/dressing from the grilled tofu over the veggies, and use your hands to massage.
