In a large soup pot, heat the olive oil over medium-high heat. Add the onion and sauté until soft and translucent, about 6-7 minutes. Add the fennel, carrots, garlic, thyme sprig, and a generous pinch of sea salt and pepper. Cook until the carrots begin to soften, about 10 minutes, stirring often. Add the green cabbage and cook 2 more minutes.
Add the apple cider vinegar and let cook 2 minutes, while stirring. Add the vegetable broth and the garbanzo beans, lower the heat, and let simmer for 10-15 minutes, until the flavors are well blended and the vegetables are cooked, but still hold their shape. Remove from the heat. Add the spinach and the lemon juice. Season to taste with sea salt and pepper. Serve with crusty bread. Oh, my.
