In a large pot over medium heat, heat the oil and then add in the onion and carrot. Saute, stirring occasionally, for 5 minutes or until the veggies begin to soften.
Add in the garlic and saute for another couple minutes.
Add in the butternut squash, potatoes, zucchini, and cabbage as well as the salt and spices. Stir to mix it all up.
Add in the broth, tomatoes (juices and all), and the thyme. Stir and bring to a boil. Reduce heat to medium and simmer for 10 minutes.
Add in the kale, stir, and simmer for an additional 10 minutes. Once the kale is fully wilted, the soup is ready.
Discard the thyme sprigs before serving and add in a bit more salt and pepper if needed.
