Oh my gosh - so good!! I think my husband was expecting to dislike this since there wasn't any dairy in it, but we both loved it and it totally satisfied my buffalo craving! I did make some changes though - in addition to the 3 stalks celery, I also added one chopped carrot and one peeled/diced medium baking potato. I sautéed the carrot and celery together for awhile before adding the potato for a little bit with some water to prevent sticking. I made the soup base with a little extra nutritional yeast, then simmered for about 30 minutes. I scooped out the veggies and put back in the vitamix to puree. Then reheated everything with the sour cream. I also left out the vegan chicken altogether because I couldn't find the brand I wanted - didn't miss it but I'm going to try with chicken next time. So good though! Thank you!
