2 tablespoons olive oil
¼ cup barley
2 pounds butcher steak, cut into small cubes
2 medium onions, diced
2 cups carrots, sliced
2 cups celery, sliced
2 cups potatoes, diced
8 cups beef bouillon (made from powder or liquid concentrate is fine)
Add all ingredients into a large slow cooker. You may add a little more liquid, if necessary, to cover. Cook on high for 2 hours, then turn down to medium for 4 (you can let it cook longer if that fits your schedule better), stirring occasionally.
This is even better reheated the next day, and also freezes well.
