Low Salt or Salt free strained soup RECIPIES

I started the strained soups this week as week 2 post op. I looked on here for a few ideas, but not really finding anything. I can not have any chunks, lumps, or clumps, in my soups. Also, I can not do alot of salt, as that made me gain weight. I would like homeade soup recipie ideas only. Not what I can have because I know what I can have, but they have toooo much salt in them. If you can help me that would BE great!

I would like to know how to make a potato soup salt free. Im not much of a cook, but would like any help I could get to get the salt out of the diet or the less the better. Thanks!

 Found this..maybe it will help! I booked marked it for myself to give some a try as well.
