more of a general suggestion than a recipe: use bok choy! it goes well in almost anything and has a very mild flavor. I like to make a chicken soup with Bok choy, mushrooms, onions, and potatoes, but you can basically mix and match almost any vegetables that you like. I usually precook cut up chicken and then just throw it and whatever vegetables all together into a pot with water or broth and let it cook for a few hours until everything's all become one soup. for spices I'm usually lazy and do some simple garlic and salt.
