Lenny, there are quite a few soup recipes in the low carb recipes folder, also have you tried wiflib's leek and chicken soup??
You can also make a chicken noodle soup = chicken bouillon, add chunky low carb veggies, chicken cut into chunks and just before serving add shirataki noodles (you can now buy them from H&B as well, so thats handy for some)
You can make comforting, creamy soups, eg courgette soup, just fry chopped onion in some butter, add sliced courgettes, salt, pepper, herbs, bouillon powder, a little bit of water, simmer for 10 mins, then puree with stick blender, add cream and its ready - you can do this with other veggies too, eg cauliflower, broccoli, or mixed veggies, throw in a carrot, just one wont make you spike, then puree but leave a few chunks and there you have a perfect wholesome thick veetable soup, a little curry powder or Magi liquid seasoning addes is nice as well.
