Still ISO: Pretzel Soup Recipe

We had a version of this at a workshop luncheon a number of years ago and it fabulous!  I’ve never found the recipe that sounds like the right thing.  It was very creamy with what appeared to be dumplings (?) made from pretzels???  They said I could have the recipe if I gave them an envelope with my address on it.  I did, with a stamp, and have never received the recipe….  Does this sound familiar to anyone yet?  I’m sure I’ve asked here before years ago to no avail…. Thanks for any input…. Wish I could just forget about that blasted soup!
