Char a brown rice tortilla on the stovetop. In a bowl, combine the kale with tamari, the juice from the lemon, and olive oil, massaging until the kale softens. Sprinkle the massaged kale with nutritional yeast. Layer the massaged kale, sliced tomato, sliced avocado, and habanero sauce onto the charred tortilla. Roll or fold the tortilla and serve immediately.
