I have no clue where I got this recipe but it is strikingly like one that we had at a sidewalk café in Paris when we took Hannah and Rose in 2001. That restaurant was a wonderful introduction to French food for the girls, not to mention that they got to see the tradition of taking your dog into a restaurant. We also will never forget the young man who sat near us and dropped practically every utensil in reach while knocking things over with his elbows when picking them up.
