Just the recipe I crave when fall sets in (although I have done a "summer" version with summer squash and other seasonal veggies). I prefer to make it in the crockpot just for the fragrance. And , which I think is my best alteration, I sub low-sodium V8 ('m fond of the spicy version) for the veg broth. It adds more and richer flavor (plus some nutrients). I also add bay leaves to deepen the flavor - but I'm a sucker for bay leaves.
It was a good basic soup which it was intended for and that was to use up a lot of existing things in your fridge and freezer. The taste was good, not exceptional. I subbed a few things out like edamame for green beans since I didn't have those and didn't have mushrooms. It made a lot of soup so we have a lot of servings left but that's ok. Not sure I'd make it again though
