Plating technique: In culinary school we learned that appealing plates are just as important as the taste! In the center of your serving plate, place a round ring (biscuit cutter or a round cookie cutter, large mason jar lid,etc) and fill the ring with ratatouille. Press down on the edges to fill the ring tightly. Gently remove the ring, and voila! You have a perfectly shaped circle of ratatouille in the center of your plate.
