Step 1
Heat olive oil in a large stockpot over medium heat. Add onions and 1/2 of the garlic and cook until slightly softened, about 5 minutes. Stir in cumin, chile powder, cinnamon, turmeric, cloves, coriander, and ginger and cook for a few seconds. Add vegetable stock, tomatoes with their juice, pumpkin, sweet potato, celery, carrot, turnip, and green beans. Season with salt and pepper. Bring to a boil, reduce heat, and simmer until vegetables are just tender, 15 to 20 minutes.
