In a large nonstick saucepan, saute the beef, onion and salt in oil for 4-5 minutes or until meat is no longer pink. Stir in the potatoes, broth, steak sauce, chili powder, cumin and cayenne. Bring to a boil. Reduce the heat; cover and simmer for 30-35 minutes or until the potatoes are tender. Garnish with parsley.
