The main herbs used in ash reshteh are spinach, parsley and cilantro but if you have other herbs such as leek or green onions (the green part) add them too. You'll need one cup of each: spinach, parsley and cilantro, all chopped very well and thick stems removes. I always chop the thinner stems as they are full of flavor. Use them in this recipe exactly the same way that you do with dried herbs.
