In a large pot, combine peas, water, barley, bay leaves, salt, soy sauce, oregano, garlic, rosemary and cumin. Bring it to a boil and cover and let it simmer at low for 25-30 minutes.
Keep stirring in between to make sure it doesn't stick to surface.
Add carrots and onions. Cover and simmer for another 30 minutes till vegetables get tender. Check periodically, add water if needed. Discard bay leaves and turn it into a fine paste in food processor.
Put it back in the pot. Taste and adjust salt. Heat it up and serve garnished with green onions and black pepper. If you feel consistency too thick, then add water and boil nicely. Adjust seasonings.
