Adapted by Smitten Kitchen from a recipe originally in 3/2008 Gourmet. A great way to use up excess zuke and tomatoes. I use brown rice and add feta cheese and a bit of Greek oregano to mine. Save dirty pans by cooking the rice in the skillet you will use later for the onions, and cover your baking sheets with parchment; foil reacts with the acid in tomatoes. You'll get fewer servings if having it as a vegetarian main course.
