No there are no syn free soups other than those you make yourself. By the way can you keep questions about syn values to the syn values sub-forum so that Starlight or Irene don't then have to spend the time moving them. Thanks!
Make your own and freeze for when you are short on time!
Tinned soups are so chock full of salt, they are not really very good for you and I for one, wouldn't waste a B choice on them!
I made spicy squash soup yesterday, apart from chopping the squash (two mins) waiting 40 mins while it roasted, all I needed to do was blend it (two mins). Three hearty portions of superfree soup in 4 mins.
Sorry I haven't answered your question but just thought I'd let you know how easy it is to make your own, much healthier, soup!
