This is a great meatless meal. I used baby portabellas; the big ones weren't available, but the babies were fine. My son hates pearl onions, so in a panic I threw in a few cups of frozen chopped rutabaga (yes, they have that now!). It was really good. The sauce was more soupy than I like, next time I'll decrease the broth by at least a half cup. Alternatively you could more flour in the binding.
