Barley & Bean Soup (Ash e jow)

Why I Love This Recipe
FEATURING: Onion, garlic, leafy greens (kale, kohlrabi leaves, swiss chard, or spinach), coriander, parsley and mint.
This is a Persian/Iranian recipe that I found on Ricardo Cuisine and adapted slightly. I usually make it on the stove but you can easily make it in a slow cooker (see link to original recipe for instructions).
You can freeze this recipe without the garnish.
