I always wonder why restaurant soup is so awful, when it's so easy to make good soup. I think they use soup base and lots of packaged stuff.
I was taught to make lettuce soup by a French woman long ago, it is one of my favorites. I love split pea soup, and I love posole. And it's always good to just heat up some good chicken broth and add whatever veggies you have on hand to make a good vegetable soup.
I have a recipe from an old cookbook for some tiny dumplings. They puff up like a dumpling, but taste like a good buttery noodle. I like to put those in a simple vegetable soup. Yummmm -- it's getting colder around here. Good time to start making soup.
