In a large soup pot, heat olive oil over medium-high heat. Add onions, pepper, celery, apples, and sausage. Sauté, stirring, until onion is just tender.

Reduce heat to medium-low. Add kale, garlic, and cumin; cover and continue cooking for two minutes.

Add remaining ingredients; cover and cook for 15 to 20 minutes, until vegetables are tender.

Taste and adjust salt, pepper and cumin, as needed.
