Heat oil in a large stew pot over medium heat. Cook and stir sliced chorizo until slightly brown and the oil takes on color, 5 to 6 minutes. Add onion, bacon, and garlic; cook until onion is soft and bacon is crisp, about 5 minutes. Add debreziner sausage and peppers and cook until mixture is smooth and soft, about 5 minutes more.

Stir in crushed tomatoes, white beans, beef stock, tomato paste, and ketchup. Season with savory, salt, pepper, cayenne, and bay leaves. Add flour to thicken and simmer, half-covered, until flavors combine, about 40 minutes. Season with salt and pepper.
