Crumble tempeh with your hands into a bowl. Add peanut butter, tamari, hot sauce, lime juice, and ginger. Stir to combine.
In a separate mixing bowl, combine kale and cabbage. Top with lemon juice, vinegar, oil, and tamari. Massage gently with your hands, taste, and add salt and pepper, if needed.
Assemble the sandwiches with a layer of crumbled tempeh, then top with the kale and cabbage mixture, and enjoy!
