This baked ratatouille is also known as confit byaldi, created by Chef Thomas Keller and the inspiration to the ratatouille dish from the Pixar movie, Ratatouille. It consists of layers of zucchini, squash, eggplant, and tomatoes shingled on top of a layer of piperade sauce made of red bell pepper, tomatoes, aromatics, and herbs. This dish is simple, refreshing, and super tasty.
