No, I didn't see the movie, but I made fatfreevegan.com's Roasted Ratatouille a couple of weeks ago and it was quite good.
I doubled the recipe and ended up with a metric assload of roasted vegetables. Seriously. I still have some left and have no idea what to do with it because no one wants to eat it anymore. We all have it coming out of our ears.
I liked this because it wasn't vegetablescookedinsauce, where everything tastes the same. It was nice to be able to taste the flavor of each vegetable and the grape tomatoes really made the whole thing pop (I'm not a fan of cooked tomatoes, but I actually looked forward to getting a forkful with tomato in it from this dish). I also used yellow and orange peppers, so the dish had a lot of color going on.
