A good bowl of soup is always a good thing and a great way to eat lots of lovely veg if you are someone that usually doesn't. Add pearl barley and I say this soup just has to be good for you. Pearl barley is similar to wheat in its caloric, protein, vitamin and mineral content and is great for adding to soups and stews.
Pearl barley does take a bit of cooking though so you will need to rinse it then into a saucepan with plenty of cold water. Cover with a lid, bring to a boil for 10 minutes then reduce the heat and simmer for about 20-25 minutes until tender before adding to your soup.
