The ratatouille is a traditional vegetable dish of the French cuisine. In particular, it originates in Nice, a lovely town in Provence in the south of France. It is made with summer vegetables, like aubergines, courgettes, and tomatoes which are first cooked separately, then combined and cooked slowly until they become very soft.
This recipe offers a quicker and simple way to prepare this delicious dish. In fact, the vegetables are just sliced and layered in a casserole with a base of tomato sauce, and then oven-baked. It's a healthy recipe that you can serve as a side dish or a main paired with toasted bread or even rice. Because it has few and simple ingredients, it is suitable for vegetarians and vegans and it is dairy-free and gluten-free.
