Use leftovers from our Spiced Steak Kebabs to make this hearty soup.
Remove beef and vegetables from kebabs. Halve beef pieces and mushrooms and add beef and vegetables to a large heavy pot, along with carrots, potato, and garlic; toss with flour. Add tomato, tomato paste, bay leaves, and water; season with salt and pepper. Bring mixture to a boil over high; cover, reduce to low, and simmer rapidly until meat is tender, about 40 minutes. Discard bay leaves. Season to taste with salt and pepper and serve topped with parsley.
