Mushroom-Tomato Bisque

My son forgot his lunch today so I brought it to the middle school. While walking down the hall to the office, I smelled this soup and had to ask for the recipe! The cooking teacher said this is what the 8th graders had made. I am posting it here so that I don't lose it! It's originally from a magazine (not sure which one) in the holiday appetizer section, 1996. PS-Yes, of course I told her about Recipezaar!
