Rinse the dried red kidney beans, then soak them overnight in plenty of water. Drain and set aside.

In a large soup pot or Dutch oven, heat the vegetable oil over medium heat. Add the diced onion, celery, and green bell pepper. Sauté for 5-6 minutes, or until the vegetables are soft.

Stir in the minced garlic, sliced smoked sausage, bay leaves, dried thyme, paprika, cayenne pepper, salt, and black pepper. Cook for another 2-3 minutes.

Add the soaked and drained beans to the pot. Pour in the chicken or vegetable broth, stir well, and bring to a boil.

Reduce heat to low, cover, and simmer gently for 60-75 minutes, stirring occasionally, until the beans are tender and the mixture is creamy. Add small amounts of water if the mixture gets too thick.

While the beans cook, prepare the rice. In a small saucepan, add the rice and 4 cups of water with a pinch of salt. Bring to a boil, reduce heat, cover, and simmer for 18-20 minutes, or until the rice is tender and water is absorbed. Fluff with a fork.

When the beans are done, remove the bay leaves. Taste and adjust salt or pepper as needed.

Serve the beans and sausage over the cooked rice. Garnish with fresh parsley and sliced scallions.
