Place the bacon, pork mince, artichokes, potatoes, celery, onion, leek, spinach and garlic into a large saucepan. Pour in the chicken stock and season with parsley, basil, oregano, cayenne pepper, paprika, salt and pepper. Cover and bring to a simmer over medium-high heat. Reduce heat to medium-low and simmer 45 minutes.
Stir the flour into the water until no lumps remain. Stir into the simmering soup and continue simmering, covered, 30 minutes until thickened, stirring occasionally.
