Combine the vegetable base and 8 cups water in a saucepan. Bring to a simmer, whisking to dissolve the base. Set aside.
Place a Dutch oven or soup pot over medium-high heat. Add the butter substitute and olive oil and heat until melted. Add the carrots, celery and onions and season with salt and pepper. Saute until tender, about 5 minutes. Tie the thyme and rosemary into a bundle with kitchen string and add it to the pot along with the garlic. Cook for 1 minute more.
3. Add the beans and their liquid, the lemon zest and vegetable stock. Bring to a simmer and cook until the beans are tender, about 10 minutes. Add the kale, season with salt and pepper and simmer until the kale has wilted and softened a bit, 7 to 8 minutes.
Divide the soup among bowls and drizzle with olive oil.
