This is a sophisticated version of my favorite cream of tomato soup...Mom never served this! I had to make some alterations to the recipe because I didn't have some of the ingredients..only a couple stalks of celery, whole milk instead of 1/2 and 1/2,and no fresh chilies, so I used canned...but the finished product was delicious anyway. The pesto was my favorite aspect of this soup and I know it will be drizzled on other things as well. I think it's the pumpkin seeds that create such a mysterious taste. We had this reheated the next day, enjoying the leftovers. thanks ellie2!
