I made ratatouille (of a sort) for dinner last night. We don't really like eggplant so much, so mine has zucchini, tomatoes and onions. That's all seasoned with olive oil and salt and pepper. Then it's topped with some mozzarella, parmesan and bread crumbs (also mixed with a little olive oil).
This is what it looked like before it went into the oven. It looked almost exactly the same when it came out (40 minutes at 400º), so just look at the same shot twice.
This guy helped.
