Instructions

1. Prepare your vegetables: Peel and dice the carrots, celery, onion, garlic, and potatoes. Trim and cut the green beans. Chop the kale or spinach if using.
2. Sauté the aromatics (optional): For a deeper flavor, heat olive oil in a skillet over medium heat and sauté the onion and garlic until translucent and fragrant, about 3-4 minutes. This step is optional but highly recommended.
3. Add ingredients to the slow cooker: Place carrots, celery, potatoes, green beans, corn, peas, diced tomatoes with juice, sautéed onion and garlic (if done), and vegetable broth into the slow cooker.
4. Season the soup: Sprinkle in dried thyme, oregano, smoked paprika, salt, and pepper. Stir well to combine all ingredients.
5. Cook low and slow: Cover and cook on low for 6-8 hours, or on high for 3-4 hours. The vegetables should be tender and flavors well blended.
6. Add greens and lemon juice: About 15 minutes before serving, stir in the chopped kale or spinach and lemon juice. Cover and continue cooking until greens are wilted.
7. Final taste and adjust: Taste the soup and adjust seasoning with additional salt, pepper, or lemon juice if desired.
8. Serve and enjoy: Ladle the soup into bowls and serve warm with your favorite bread or crackers.
