Preheat oven to 425°F (220°C). Combine all marinade/dressing ingredients in a jar and shake well. Marinate the tempeh in about half of the dressing for at least 30 minutes.
Place marinated tempeh (with its marinade) on one half of a baking sheet. Add the diced sweet potatoes to the other half. Drizzle the sweet potatoes with a little olive oil and sprinkle with salt. Roast for 25-30 minutes, or until both are browned and tender. Once roasted, toss the tempeh with a little more dressing.
In a bowl, combine the kale with a little of the remaining dressing. Add the avocado and massage the kale and avocado together until the avocado is somewhat smashed and the kale is tender and slightly creamy.
Assemble the bowls by combining the roasted tempeh, sweet potatoes, massaged kale, and sauerkraut. Add any desired optional toppings or add-ins and serve.
Notes
This recipe is great for meal prep. Keep dressing separate when storing leftovers and drizzle just before serving.
