Heat the oil in a soup pan and cook the yellow or white onion, carrot, celery, garlic and green onion.  Cook about 5 minutes, stirring, until the onion is softened.  Add the spice mix, spinach and other vegetables (could be zucchini, cabbage, kale, green beans, yellow beans, whatever you have around). cook another minute or two, stirring.

Add the chicken broth and the rice and cook simmering for 25 minutes or so. You could also add cooked beans if you like, or add them instead of the rice. Or some diced potatoes.  Or pasta.  Or skip the starch altogether if you wanted a side soup rather than a main dish.  Most people would probably enjoy some diced cooked chicken or you could add some raw chicken pieces and then remove then after they are cooked (probably about 30 minutes), shred the meat and return it to the pot.
