Heat the vegetable oil in a large pot over medium heat, and cook the onion until lightly browned. Place sausage in the pot, and pour in water. Mix in cabbage, carrots, celery, rice, beans, tomato sauce, and crushed tomatoes. Dissolve bouillon in the mixture. Season with salt, bay leaf, and thyme. Bring to a boil. Reduce heat to low, and cook at least 1 hour, until vegetables are tender and rice is cooked.
