Place the cubed tofu in a bowl with the tamari, garlic and sesame seeds and stir to combine. Leave to marinate for at least 15 minutes.
Once the tofu has marinated, heat the oil in a large frying pan and fry the tofu ensuring all sides are cooked and crispy.
Remove the tofu from the pan and quickly add another dash of oil, heat and then add the Brussel sprouts, kale and purple cabbage. Toss until heated through and starting to become crispy.
Season with salt & pepper, sprinkle with extra sesame seeds and serve immediately.
