In a hot pan with oil, stir the carrot and zucchini together. Then season them with salt, oregano, basil, and ground garlic.
Keep on cooking them and after about 8 min. stir in the tomato sauce, and about 8 min. after turn of the fire.
Then gently stir in the spinach, put all this in a plate and set aside.
In the same pan used before, add some more oil and cook the eggplant slices about 5 minutes each side.
Then, in a pie mold place first a layer of eggplant slices, then half of the carrot and zucchini, then some grated cheese and do this all over again, a layer of eggplant then carrot and zucchini and the cheese to top it off.
