Or something like it. The French eat it cold. Generally speaking, although there are billions of recipes, each ingredient is sauteed separately and then added together in the sauce, briefly simmered and then let sit overnight. This way it does not turn into the mush you usually get called ratatouille. This isn’t really ratatouille since there is no zucchini and little eggplant. And it has mushrooms not usually found in ratatouille. Come to think of it, it’s not really ratatouille at all. I ate it with ramen noodles. The more I think of it, the less like ratatouille it gets. None the less it was delicious. Eaten hot.
