What are your favorite miso soup combinations?

I love miso soup. One of my favorite things to add is cubed sweet potato and a teaspoon of tahini for added creaminess. Then I have different variations on that: sweet potato/ wakame/ leek/tahini sweet potato/ bok choy/ daikon/ tahini sweet potato bok choy/ bean sprouts/ tahini sweet potato/ asparagus/ wakame/ tahini (If you can't tell I love sweet potato=) Then I also like: eggplant/mushroom sweet corn/ wakame/ zucchini I usually always use white miso. I like red miso better in other types of cooking. Sometimes I add tofu too. I'd love other ideas!
