Ingredients for four to six people:
The white beans are soaked overnight in cold water. Then drained and boiled in water for an hour.
Prepare and slice the vegetables. Place the vegetables (except the leeks) in a saucepan with the beans and the garni and add salt and pepper. Boil and then add the single piece of flat bacon. Cook for an hour and then add the leeks with additional pepper. Cook for another hour.
Take out the bouquet garni. Remove the bacon and take of the rind. Dice the bacon. Remove the skin of the chitterling sausages and cut into slices. Place the sausages onto each plate, covering them with the vegetable soup. Add the bacon and finely chopped parsley to each serving.
