In a large stock pot cook the bacon until crispy. Remove the cooked bacon and drain on paper towels. Remove all but 2 tablespoons of the bacon fat and reserve the remaining.
Brown the pork in the bacon fat on medium-low heat. Do this in small batches until all it's all browned. Season each batch with a pinch of salt and pepper. Remove from pan and place in a large bowl.
Add the kielbasa and brown. Once browned add to the bowl with the pork.
Season the chicken with a pinch of salt and pepper on each piece. Add a little more bacon fat to the pan and brown the chicken. This will take 5-8 for the first side. Turn over and cook for another 3 minutes. Remove from the pan and place in the bowl with the other meats.
If needed, add a little more bacon fat to the pan and saute the onions until translucent. Add the carrots and garlic and cook for another minute. Deglaze the pan with the wine, scraping up the brown bits.
Stir in the bay leaves, herbs de Provence, tomatoes, tomato paste, salt and, pepper. Add the meats back to the pan along with the cooked bacon. Stir in the cooked beans and cover with the chicken stock.
Cover the stock pot with the lid and place in a preheated 350-degree oven for 45 minutes. Remove from the oven and stir in the chopped kale. Top the stew with the breadcrumb mixture.
Increase the temperature to 400 degrees and cook for an additional 30 minutes or until the breadcrumbs are browned. Remove from oven and serve in large bowls with fresh baguettes.
