My favorite raw soup is extreeeemely simple so I am not sure if it is what you are looking for. But aside from fruit, it is my favorite thing to eat.
I simply blend some water together a big handful of baby spinach, one large tomato, a cucumber, a handful of cilatro and a yellow bell pepper. (Obviously you can substitue for whatever green/herb/ bell pepper you like) And I add a little bit of kosher salt, which is up to you. It's a very green soup, but when you taste it, you mostly taste the bell pepper which is very sweet and refreshing. I think the soup works better with something like baby spinach or lettuce rather than kale or a really strong green. Anyways, I think it's really good, so I hope that helps.
