Begin by preparing all the vegetables. Chop the cabbage, onion, carrots, celery, bell pepper, and garlic as indicated in the ingredients list.
In a large pot, heat the olive oil over medium heat. Add the chopped onion, carrot, and celery. Sauté for about 5 minutes until the vegetables are softened.
Stir in the bell pepper, garlic, and green beans, and cook for another 3-4 minutes.
Add the chopped cabbage to the pot, stirring it in to mix well with the other vegetables.
Pour in the diced tomatoes (with their juices) and vegetable broth. Stir to combine all ingredients.
Season the mixture with thyme, basil, salt, and black pepper. Bring the soup to a boil.
Once boiling, reduce the heat to low and let it simmer for about 30 minutes or until the vegetables are tender.
Taste and adjust seasoning as necessary. If you prefer a smoother texture, you can blend a portion of the soup and then return it to the pot.
Serve hot and enjoy your healthy fat-burning cabbage soup!
