Ncage, would love to help as I am sure many here would, but it would help if you gave some details about the soup.
Perhaps you could deconstruct it a tad. By that I mean tell us what is in it that you can figure out? Are there chicken pieces? If so, what size? How about veggies? Is there okra, celery, maybe tomatoes, perhaps some rice. Is the soup very liquidy and what is the color? And most importantly, what can you taste in it?
That is one approach.
Or can go in, buy the soup for a few days, and ask about the recipe.
If not the full recipe they will probably tell you a bit about it.
Just a few ideas that strike me at this early hour.
Good luck and God bless.
