Return the pan to the oven and bake for an additional 10–20 minutes, or until the veggies are roasted to your liking. For a crispier finish, broil for 1 minute, watch closely to prevent burning.
Sliced red, green or yellow bell peppers can be added in addition to or substituted for the tomato.
After removing from oven sprinkle with finely grated parmesan cheese and chopped flat leaf parsley, optional.
