In a large pot, cook pork (or turkey) over medium-high heat until browned, breaking up with a spoon. Season with parsley, Italian seasoning, black pepper, fennel seed, paprika, and red pepper flakes. Once cooked through, drain and place sausage on a plate. Set aside.
Add olive oil and onions to the pot and cook until translucent. Add the garlic and continue to cook for another minute. Next add broth and water to the pot. Bring to a boil, then add remaining ingredients as well as the cooked pork. Reduce heat to medium-low, cover pot and let simmer.
Let contents of pot simmer for at least 30 minutes, until potatoes and carrots are cooked through. To allow flavors to combine, cook longer if possible.
Season with additional black pepper and red pepper flakes to taste. When ready to serve, sprinkle with additional parsley.
