Cut the steak into strips, put into a dish or pan and sprinkle with the salt, pepper, and paprika. Make sure all the steak is coated.
Slice the onion and pepper and set aside. In a large skillet sauté the garlic cloves. Remove from pan and discard. Raise the heat to medium high and add the steak. Sauté for about 2 minutes; turn over and sauté for 2 more minutes. Remove from pan and set aside.
Add the onions and peppers and sauté for about 5 minutes (longer for well done).
Add the meat back to the pan. Add the cornstarch and soy sauce to the beef broth and add to the pan. Bring to a boil. Reduce heat and cook for 5 more minutes or until sauce thickens. Serve over rice or noodles. Adjust salt and pepper as needed.
