Prepare the Vegetables: Begin by preparing all your vegetables. Slice the carrot into rounds, dice the onion and celery, and mince the garlic. Set everything aside for when you're ready to cook.
Sauté the Aromatics: In a large pot, heat 1 tsp of olive oil over medium heat. Add the chopped onion, garlic, carrot slices, and celery. Sauté for about 5-7 minutes, stirring occasionally, until the vegetables soften and the onion becomes translucent.
Sear the Chicken Sausages: While the vegetables cook, heat a small skillet over medium heat. Add the sliced smoked chicken sausages without any oil (they'll release enough fat). Sear them for about 5 minutes, stirring occasionally, until they are browned on both sides. Set the sausages aside for later.
Add the Chicken and Seasonings: After the vegetables have softened, stir in the shredded chicken breast and white beans. Season with oregano, salt, and black pepper. Let it cook for 2 minutes to blend the flavors.
Simmer: Pour the chicken broth into the pot and bring the mixture to a boil. Once it boils, reduce the heat to a gentle simmer.
Add the Kale and Sausages: About 5 minutes before the soup is done, add the chopped kale and the browned chicken sausages. Stir them into the soup, and let it cook until the kale is wilted and the sausages have heated through, about 5-7 minutes.
Taste and Adjust: Taste the soup and adjust seasoning if needed. Add more salt or pepper according to your preference.
Serve: Once the kale is tender and all the flavors have combined, the soup is ready to serve. Ladle into bowls and enjoy it hot!
