Eggplant Parmesan is Italian cuisine. It is made with a shallow or deep fried slice of eggplant, layered with cheese and tomato or marinara sauce, then baked. Eggplant Parmesan Sandwich is tangy and cheesy. This is my favourite sandwich of all time. I used fresh homemade Marinara Sauce in this recipe. I have already shared recipe of Homemade Marinara Sauce.
