Check out this link, if you need to jump-start your miso soup creativity! http://www.japanesefoodreport.com/2009/12/how-to-cook-miso-soup-66-ways.html
I bought a large kabocha squash at the store, roasted it whole in the oven (after stabbing it several times with a large knife to avoid catastrophic squash explosion), and used it in a variety of dishes this week, but I have already made this miso soup several times over and it is just delightful.
I tossed cubed firm tofu in whole wheat flour and gomashio, which is a japanese condiment that I bought at a local co-op but you could make it yourself easily. It is comprised of salt, toasted sesame seeds, and mine also has seaweed in it. I fried the tofu in vegetable oil and placed it on a paper towel to drain. I sliced some roasted kabocha squash into bite-sized pieces, and blanched several swiss chard leaves in a pot of boiling water, then sliced them lengthwise so they were also more bite-sized. The swiss chard, kabocha, and some wakame were then added to the miso soup broth, and served at last with the tofu added in just before serving. The kabocha added a little color to the broth and was perfect with the wakame and chard. This fried tofu, additionally, was probably the most satisfying fried tofu I've ever made--I'll definitely use the gomashio in the future!
