Although I own Ms. Katzen's wonderful Moosewood cookbook, I lent it to a friend years ago and have yet to get it back. So, I knew exactly what recipe I wanted for Ratatouille and this definitely is the one. Although I made a few minor substitutions, it came out delicious and rustic and deeply flavored. I didn't use tomato juice or tomato paste, but rather I used about 8 oz of tomato puree with 1/3 cup water. Worked great! Thanks for a fantastic classic recipe from one of the best vegetarian cookbooks ever!
