So you made that soup, now you need to do something with that soup-chicken. These pages show what I did with some of them. You can serve soup-chicken with whatever you want. I will often serve the soup-vegetables right there with that chicken, but something extra is not unthinkable.
Since mid-2019 I no longer cook these chicken legs to death. I have been removing them from the soup after about 15-20 minutes simmering and finishing them by pan-frying or oven-roasting. That gives them a lot more flavor than boiling alone. See: roasted soup-chicken.
Now why didn't I think about this before?
