Heat a Dutch oven or stock pot over medium heat. Add your olive oil.
Add the sausage and sauté for 5 minutes until browned. Remove from the pot.
Add the onions, leek, garlic, celery, carrots, and potatoes. Seasoning with salt and pepper. Sauté for 10 minutes until the onions are translucent and the vegetables beginning to get tender.
Add the cabbage, bay leaves, and herbs to the pot. Stir to combine.
Add the sausage back to the pot. Add 3 cups of water, or enough to make sure all of the ingredients are fully submerged.
Cover and allow to simmer for 45 minutes.
Serve with a sprinkle of chili flakes and crusty bread. Enjoy!
