Preheat the oven to 400 F. Lightly oil a 2 quart baking dish. In a large sauté pan, heat the olive oil and add the onion, veggies and carrot and bring to a sizzle over high heat, then reduce the heat to medium. Stir often until the carrot is soft, about 5 minutes. Add the herbs and cubed bread, turn to mix and transfer to the baking dish.
