You’re right about the literal meaning — it translates to “again the same soup and the same bowl.” It’s a Persian idiom people use when something was supposed to change or improve, but it ends up being exactly the same as before. Kind of like saying “same old story” in English.
So yes, you could definitely use it jokingly if your friend keeps giving you the same answer — it fits perfectly in that situation!
