In a large bowl, add the puréed tomato flesh, onion, garlic, rice, mint, basil, parsley, tomato juice and 50 ml (1/4 cups) olive oil. Season with salt and pepper. Stir.
Add the filling to the tomatoes and green peppers. Fill them ⅔ of the way, since the filling will fluff up when baking. Add any remaining filling in the baking pan. Season with salt and pepper, drizzle with the remaining 50 ml (1/4 cups) of olive oil and add the lukewarm water.
Cover the tomatoes and green peppers with their caps. Cover the baking pan with aluminum foil and bake for 1 ½ hours. Remove the aluminum foil for the final 15 minutes of baking.
When ready, remove from the oven and set aside for 10 minutes before serving. Serve with Greek feta cheese for a completely authentic Greek taste!
