I'm having a (super casual) party tomorrow night for some vegetarians. I'm making black bean soup and cornbread, and someone is bringing chips and guacamole. I'd like to have one more vegetable side dish to serve with the soup... I was thinking of something with sweet potatoes, but they seem a little mushy given the mushiness of the soup. Any thoughts on what would be a good, relatively easy to prep, extra vegetarian dish?
