A vegetable stew from the Provençal region of France is called ratatouille. Traditionally, ratatouille is made with tomato, eggplant, zucchini, and peppers, as well as onion, garlic, and herbs.
A classic ratatouille contains summer vegetables that are native to Provence, where the dish originated. It's a hearty, healthy, and simple stew that can be the main entree or a side dish. The carefully arranged layers of thinly sliced vegetables featured in the 2007 animated film Ratatouille aren't strictly traditional, but this is a dish with many acceptable variations. The word itself stems from the French touiller, "to stir up."
