Brown the beef with your Cajun Seasoning, drain off fat then remove to a bowl. Cook the onion, carrots, celery and garlic until starting to soften, then add the tomatoes, broth, and cabbage. Add the beef back in, and enough water to cover. Cook 15 minutes, then add the rice or barley. Cook another 15 minutes, stirring occasionally, until the rice is done and the cabbage is cooked to your liking. ***IF YOU ARE USING BARLEY, IT WILL TAKE 30-45 MINUTES TO COOK. ADD THE CABBAGE ABOUT 30 MINUTES IN BEFORE ADDING THE CABBAGE. Add salt and black pepper to taste.
