This isn't a soup but I think it counts anyway. I've thought about ditching meat completely from time to time. This recipe for Vegetarian Chili completely fooled me and I didn't miss the meat. It is thick and substantial. (I found the bulgur wheat at Whole Foods.)
I made it for my in-laws this past weekend and they had seconds. The truest compliment to a cook. After it was simmering on the counter I thought about wanting cornbread to go with it so I found this recipe for cornbread muffins. The muffins were a little dense and I would like them lighter. But overall they were very easy and delicious.
I would make both again soon, maybe when there is snow on the ground.
