Step 1

In a soup pot over high heat, heat oil. Add beef, onion, mushrooms, and carrots and sauté 6 to 8 minutes, or until they begin to brown. Add diced tomatoes including the liquid, beef broth, salt, and pepper; bring to a boil. Reduce heat and simmer on low 30 minutes, or until beef is tender, stirring occasionally.

Step 2

Add barley and simmer an additional 15 to 20 minutes, or until barley is tender. Serve immediately.
