Season beef with salt and pepper. Heat oil in a large pot then add beef and brown.
Add onions, garlic, carrots and tomato paste and cook for 2-3 minutes until the onion softens.
Add beef broth, water, oregano, bay leaf and barley.
Bring to a boil and turn the heat down to simmer.
Cook until the beef is tender, about 1 ½ to 2 hours. Add extra salt as needed and garnish with chopped parsley.
